Hot Tub Filter Cleaning Brush? Top 50 Best Answers

The best way to ensure the water stays clear in a spa is to ensure that everyone using the spa takes a shower first. If it doesn’t, only the spa filter will keep the water from turning into “Soup of the People”. Inevitably, the filter quickly clogs and stops doing its job, which is one of the reasons why cleaning spa filters is so important – and there’s another.

The water in virtually every home contains mineral salts that leave deposits that are difficult to remove. This is scale that can clog the spa pump and stain the tub liner. It collects in the filter media and can be difficult to remove.

Vinegar is a weak acid that dissolves scale and is safe enough to drink, so cleaning hot tub filters with vinegar is one of the methods recommended by spa maintenance professionals.

Products and techniques for cleaning spa filters

Treating your spa filter with vinegar is not the only way to clean it, and depending on the water characteristics, it may not be the best method. Other cleaning agents are:

Bleach: Household bleach is a disinfectant that is particularly effective at killing pathogens brought in by spa-goers, as well as algae spores and other harmful microbes.

Detergent: Soaking your spa filter in detergent will do to the filter what it does to your clothes. Spa professionals generally recommend using trisodium phosphate instead of household cleaners. TSP is basically regular laundry detergent on steroids and is a component of some brands of dish soap, so some pros advise you to clean the spa filter with dish soap. It is important to rinse thoroughly with detergent after cleaning, otherwise foam could form in the tub water.

Hydrochloric Acid: The acid you use to maintain the pH of the spa water can also be used to clean the filter. It is better at dissolving limescale and rust stains than vinegar, but cleaning hot tub filters with muriatic acid is slightly dangerous due to the chemical’s toxicity and corrosiveness.

Commercial Filter Cleaner: Commercial filter cleaners are widely available in a variety of formulations. Some spa professionals recommend using only commercial cleaning products over household cleaners like bleach and vinegar.

You can also put your filter in the dishwasher to clean it, but only if you have a ceramic filter. A dishwasher generates enough force to damage a paper filter. The most recommended general cleaning technique is to hose down the filter, soak it in some type of cleaning solution, and rinse it out. It’s important to let it dry thoroughly before putting it back in to finish off any microbes that may still be stubbornly clinging to life.

Meet the filter you are about to clean

There’s nothing complicated about your spa filter, but it’s still a good idea to take a minute to familiarize yourself with it. Filters are cylindrical and most are made of polyester mesh, but some newer ones like the Tri-X feature a ceramic media. Both types of filters need to be cleaned regularly.

advertisement

Parts of a typical filter include:

The Media: This is the part that does the actual filtering. If you have a paper filter, the media is the white, pleated polyester paper cover that stretches from one end of the filter to the other. A ceramic filter also has a pleated cover that extends from end to end, but the cover is rigid. You can wash this type of filter in the dishwasher.

advertisement

The Core: This is the rigid inner part of the filter that gives it its structure. It is usually made of plastic and is formed into an open cylinder that fits over the water circulation standpipe in the spa’s filter compartment. Algae and mold can grow on this part of the filter, so it needs to be cleaned regularly.

advertisement

The end caps: These are also made of plastic and also need to be cleaned. In particular, the edges of the water intake openings directly behind the path of water flow can accumulate debris and harbor algae growth.

You should not use abrasive cleaners to clean the filter media, but you can use a bottle brush to scrub the inside of the core and the insides of the end cap rims. Put some washing-up liquid on the brush to quickly remove dirt and algae.

Why cleaning spa filters with vinegar is a good idea

If you have a hard water problem in your home, a simple experiment can demonstrate the effectiveness of vinegar for cleaning mineral deposits. The experiment calls for a lower-than-normal faucet, which is usually easy to find in a hard-water home. You may have thought that the low pressure was due to a problem with the pipes or faucet valve.

Remove the aerator and soak it in a small bowl of regular white distilled vinegar overnight. If you replace the aerator in the morning, you will probably be surprised by the increased flow rate. The vinegar dissolved any debris in the tiny vents, and the same goes for your spa filter. By the way, if the faucet still flows poorly, disassemble it and soak the valve in vinegar.

Vinegar is great for dissolving limescale and is safer than muriatic acid. It is also an effective disinfectant that is safer than bleach. It’s inexpensive, and you probably already have some around the house. What’s not to like?

The procedure for cleaning hot tub filters with vinegar

If you decide to clean your spa filter with vinegar, all you need is a few basic supplies, including a garden hose, a large, shallow bucket, and a gallon of white distilled vinegar.

Be sure to turn off the spa before removing the filter. Leave it out until you replace the filter, or a large piece of dirt could get sucked in and clog the pump.

Lift the filter off the water circuit standpipe. Be careful not to damage the standpipe itself as it tends to come loose with the filter. You may need to unscrew a threaded cap to detach the filter from the standpipe.

Hose down the filter media to remove large debris such as leaves and bugs.

Place the filter in a bucket large enough to lay on its side and fill the bucket with enough water to cover it.

Pour in at least 1/2 gallon of vinegar. Ideally, you want a 50/50 concentration of vinegar and water, so you may need to pour in over 1.5 liters of vinegar.

Let the filter soak for at least 3 hours. It’s better if you can leave it overnight, especially if it’s been a while since you last cleaned it.

Invert the filter after it has been soaked for approximately 2 hours to ensure all parts are evenly exposed to the cleaning solution.

Remove the filter from the bucket and rinse it thoroughly with the garden hose. Look for mineral deposits that haven’t dissolved, and if you see any, let the filter soak for a while longer.

Wait for the filter to dry before replacing it. It dries faster if you put it in the sun.

Check the standpipe inlet for debris that may have floated in before replacing the filter.

Alternative ways to clean a paper filter

Soak in Dish Soap: Some spa pros say you can clean a hot tub filter with dish soap. One way to do this is to simply add a cup of dish soap to the same amount of water instead of vinegar and let the filter soak for 24 hours. If detergent does not contain TSP, add 4 tablespoons to increase cleaning power. You can also combine the detergent and TSP with vinegar to create a double whammy that dissolves limescale, disinfects and emulsifies oils and dirt particles.

Soak in household bleach: This may be necessary if you have not had a chance to service the spa and the water has become cloudy. Bleach is one of the best disinfectants. However, repeated exposure of the filter to bleach can damage the plastic parts, so you should not use this method frequently. To clean a filter with bleach, cover the filter with 5 gallons of hot water, add 1/4 cup household bleach and soak the filter for a maximum of 2 hours, not overnight.

Use an off-the-shelf filter cleaning product: Take the guesswork out of cleaning your spa filter by using a lab-formulated product. A selection of spa filter cleaners can be found at hardware stores or spa outlets. If you buy one of these, use it according to the directions on the box.

Cleaning a ceramic filter in the dishwasher

Just like a paper filter, you can soak a ceramic filter in vinegar, dish soap, or bleach, or clean it with a commercially available filter cleaning product. However, because the filter has a rigid filter media, you also have the option of putting it in the dishwasher, and that’s even easier.

Be sure to empty the dishwasher completely and set the rinse cycle to the longest possible time. Do not add dishwashing liquid and do not activate the drying cycle. After the wash and rinse cycles are complete, remove the filter and allow it to dry for 24 hours before replacing it.

Clean spa filter with muriatic acid

The muriatic acid you use to maintain the pH of the spa water also dissolves limescale faster than vinegar. However, you might worry that such strong acid will damage the filter components. This might be true if you used it at full strength, but not if you dilute it first and limit exposure time. The recommended concentration is 1:20. That’s 1 part hydrochloric acid to 20 parts water.

Put on your gloves and goggles as muriatic acid is strong enough to burn your skin and eyes. Fill a large bucket with enough water to cover the filter, then pour in the muriatic acid. Always add acid to the water and never the other way around.

Hydrochloric acid at this concentration will dissolve most mineral deposits in 15 to 20 minutes. When the time is up, flip the filter over to ensure all sides get the same exposure and wait another 15 minutes before removing the filter and rinsing with a hose. Let it dry thoroughly before putting it back in.

Regular maintenance of your hot tub is key to ensuring your hot tub is running smoothly. To avoid problems or damage to your hot tub, your filter should be part of this regular maintenance schedule and must be kept free of dirt and debris.

Why Clean Your Hot Tub Filter?

The climate and spa usage are two major factors that affect how often you need to clean your filter. The more often you use your hot tub and the hotter the climate, the more often you will need to clean your hot tub and filter.

Don’t worry! It’s not difficult to keep your filter clean: just stick to a regular cleaning schedule throughout the year.

How often does your hot tub filter need to be cleaned?

Spa Maintenance Weekly Filter Cleaning Your filter should be flushed regularly, about twice a week, depending on your spa usage and climate. In general, the rule of thumb is to give your filter a thorough cleaning every two weeks with a filter cleaner, which will allow you to clean between the folds and remove debris. Spa Maintenance Seasonal Filter Cleaning Ideally, you should change your spa water every three months. Take the time to give your filter a thorough cleaning by rinsing and soaking it in a solution of water and a filter-specific, non-sudsing cleaner. Pro tip: It’s a good idea to always have two filters on hand. That way you always have an extra clean filter on hand when you do a deep cleaning and realize it’s time to replace the old one!

How Often Should You Replace Your Hot Tub Filter?

Regardless of how much time you spend using your hot tub each year or how much you clean, you should replace your hot tub filter every year. This ensures that the performance and efficiency of the filter is not compromised. The filter is an essential part of your hot tub.

When Should You Replace Your Hot Tub Filter?

It’s time to replace your filter when:

There are signs of use

Water does not pass through (or does not pass through smoothly)

Gets too dirty or overused

What Does a Dirty Hot Tub Filter Look Like?

Regardless of how well or how often you clean your filter, you should replace it once a year. If your hot tub gets heavy use by a lot of people, you may want to replace the hot tub’s filter more often, but the longest you should stick to is a year.

The main reason for this is that even if you don’t use the tub much and there isn’t much to filter out, the water will still flow through the filter and break down over time. This allows particles and contaminants to get through and into the pump more easily. Pumps are more expensive than filters, so it’s easier to replace the filter.

Good to know:

A dirty or overstressed filter could endanger other parts of the spa system. This is another reason why it is important to change it regularly to avoid potential costly damage to the hot tub’s internal mechanical parts.

Follow our 3 easy steps to clean a hot tub filter

Once you’ve chosen your top hot tub, you need to be knowledgeable about the care of your choice – including the filter.

“Quality hot tub filters have a molded plastic core and a pleated polyester material that traps dirt,” explains Sallie Leslie-Golding of BISHTA (opens in new tab) (The British and Irish Spa and Hot Tub Association). “The folds in the filter material increase its surface area so that more dirt can be retained.”

It’s the particles trapped in the filter that you need to remove. Here’s how to clean a hot tub filter.

1. Flush the spa filter weekly

The first step in cleaning a hot tub filter is a weekly flush. You can do this with a garden hose and the process will remove the large debris that the filter caught.

As with any part of cleaning a hot tub, turn the hot tub off first. Next, remove the filter according to the tub manufacturer’s instructions. Rinse the folds of the filter with the hose.

Allow the filter to dry completely and then replace it.

2. Thoroughly clean a spa filter

While flushing the hot tub filter weekly is an important part of hot tub maintenance, knowing how to properly clean a hot tub filter means you also need to know how to deep clean it. How often should this happen? “Depending on how often you use your hot tub, we recommend cleaning your filter twice a month,” advises Tim Snelling, sales manager at Hot Tub Hub (opens in new tab).

Soaking the hot tub filter in a filter cleaning solution thoroughly cleans it and removes contaminants, including bacteria and oils. Turn off the spa first, then remove the filter. Flush as above to remove large debris from the filter prior to deep cleaning.

Prepare the filter cleaner according to package directions in a bucket and place the filter in to soak and leave overnight.

Rinse the filter thoroughly after soaking. Let it dry completely before putting it back in.

Always make sure you read the spa manufacturer’s filter care instructions when choosing a cleaning product.

3. Replace filters regularly

It is important that you do not use your hot tub without the filter in place as dirt could damage the spa. But this means that removing the filter to clean it will prevent its use. The solution? A filter change.

“The filter material is resistant to acids and other chemicals and is expected to last up to 18 months,” says Sallie Leslie-Golding. “It is advisable to use two sets of filters alternately month on/month off so you always have a clean set ready to put back in when the other set is removed for a deep cleaning (to reduce downtime on your hot filter) . tub).

“If you don’t change your filters, they should be replaced with a new set every 12 months; whereas those used on a month-to-month rotation basis can be replaced with new ones every 24 months.”

Don’t forget that in addition to regular filter changes, knowing how to shock a hot tub and how to properly drain a hot tub should also be part of your ongoing hot tub maintenance.

Hot tub filter cleaning mistakes and how to avoid them

Not every spa owner knows how to properly clean a hot tub filter. These are the mistakes experts see most often, so you can avoid them.

Rinsing the Hot Tub Filter With a Pressure Washer: “As tempting as it may seem, we wouldn’t recommend using a pressure washer to clean your hot tub filter as it can damage the filter,” says Tim Snelling. Sallie Leslie Golding agrees. “A pressure washer should never be used to clean filters because the force of the jet will damage the fibers of the fabric in the filter mesh, rendering it unusable,” she says. The way to avoid problems? “Use a garden hose with good blasting pressure to remove the large and loose debris caught between the pleats,” says Sallie. “Either place your thumb over the end of the hose to increase water pressure, or use a spa filter brush hose attachment.”

So that’s a definite no to dish soap, laundry detergent, vinegar and bleach, all of which you might see recommended online. Also, do not put the whirlpool filter in the dishwasher.

Why is it important to clean a hot tub filter?

Regular cleaning of a hot tub filter is important because of the job it does. “Spa filters work in conjunction with the spa’s pump,” explains Tom Drakett-Cain. “As the key part of any circulation system, the pump pulls water from the spa through the filter before returning the freshly filtered water to the spa. In doing so, it collects small dirt or debris and helps keep the water clean and clear.”

Cleaning the filter removes what it caught. “If it’s not cleaned regularly, the dirt and debris will get trapped in the filter,” says Sallie Leslie-Golding. “You will eventually begin to reduce the effectiveness of the filter and the cleanliness of your water. Your sanitizer will be used up faster and will kill germs in the debris in the filter rather than in the main water of your spa where it is actually needed.”

Note that there are differences in filtration between different hot tubs. “The amount of water pumped through the filtration system will vary depending on the make and model of hot tub and the type of circulation/filtration system used,” says Sallie. Always pay attention to the manufacturer’s instructions for filter care.

Adding proper hot tub canopy ideas to your outdoor spa space can be a great way to reduce the amount of dirt and debris that also gets into your hot tub filter.

The best way to clean spa filters

A private hot tub is a great way to relax and unwind. The last thing you want to do while kicking back in your spa is thinking about how dirty the water is. Every time someone enters the hot tub, the lotions, makeup, and hair products on their body come with them and drain into the water. Showering before entering the hot tub will help remove these products. However, hair, sweat and other bodily fluids get into the water and impair its cleanliness.

Because of this, the filter is one of the most critical parts of a hot tub. Its job is to remove all impurities in the water that could affect the water quality. But a dirty filter with a lot of debris cannot filter water effectively. This leads to problems like dirty or oily water and bacterial growth. It can even lead to a broken hot tub if the water is excessively dirty, overloading the pumps or clogging the pipes.

Fortunately, there are many ways to clean hot tub filters. Some alternatives include cleaning hot tub filters with vinegar, using a homemade hot tub filter cleaner, and cleaning hot tub filters in the dishwasher. Keep your hot tub fresh, sanitized and functional by learning the best way to clean hot tub filters.

Weekly flush

The best way to clean spa filters is to be consistent. Take out the hot tub filter and rinse it with water every week to remove debris from the filter. This is just a quick clean so you don’t need to use a hot tub filter cleaner. Instead, use water from a hose or even the tap, making sure to get between the folds for a more efficient job. Do not use a pressure washer to remove residue from the filter. The water jet should be gentle enough to avoid cracking or breaking the filter. Then allow the filter to dry completely before replacing it in the spa.

The best way to clean spa filters is with a regular deep clean

In addition to the weekly flush, you should do a more thorough cleaning every month or more often if needed. Deep cleaning involves removing the filter and using a spa filter cleaning solution to remove built-up residue and contaminants that require more than just a rinse.

Regular cleaning of your hot tub filters will help keep the water clean and the equipment working properly. But I’ve always wondered, can you clean hot tub filters in a dishwasher?

Here’s what I’ve learned over time:

no You should never attempt to clean your spa filters in the dishwasher. The dishwasher is way too harsh for the filter media, and a dishwasher won’t even clean it properly because it can’t get between every crease.

But now that you know what NOT to do, let’s get to the rest of the story!

The rest of this post will discuss some important questions about properly cleaning your hot tub filters:

Can you put Whirlpool filters in a washing machine?

How do you clean hot tub filters?

How Often Should You Clean Your Hot Tub Filter?

Can you use bleach to filter hot tub filters?

Hardware store, hands down one of the best filters I’ve ever seen!

Can you put whirlpool filters in the dishwasher or washing machine?

I’ll be honest; It’s tempting to just toss your filters in the dishwasher or washing machine.

Unfortunately, these seemingly clever hacks can actually result in the need for a new filter. You should definitely avoid this “trick” if you want to save money when changing the filter!

You should never throw a pool or spa filter in the dishwasher or washing machine for the following reasons:

Dishwashers tend to eject hot water at high speeds. This may seem like a good thing, but it damages pleats (the pleats of a filter) beyond repair. Once the creases are torn, there is nothing you can do to fix them. It can also tear apart the ligaments that hold each fold together, which is also irreversible.

How do you clean hot tub filters?

The process of cleaning hot tub filters is not that bad. Once you learn how to clean them properly, you might understand why there’s no need to use the dishwasher or washing machine.

To properly clean your filter, you will need the following items:

A garden hose

Filter cleaning solution (click here to see my favorite solution on Amazon)

(Click here to see my favorite on Amazon) A hose attachment to distribute the water evenly

And here are the five steps you need to take to keep your spa filters fresh like new:

Remove the spa filter from the filter unit and place it on a solid surface. Prepare your garden hose with the optional attachment. Spray the water evenly over the outside, making sure to gently open and clean each and every crease. Do not turn the water pressure up too high as this can damage the filter. Be sure to spray slowly from top to bottom to remove all dirt from the filter. Apply the cleaning solution to the filter by spraying it evenly over the pleats. Some cleaners get mixed in when the tub’s jets are running, so always follow the directions on the bottle or container. Wait the time indicated in the instructions – most filter solutions take between 5 and 30 minutes to set. Also see the instructions here for more details. Spray the solution with water from the hose, making sure to remove any detergent. Place the filter(s) back into the assembly, seal and you’re done! You don’t need to let them dry as they will get wet in the assembly anyway. Drying them out too much can be bad for them as it can lead to cracking and flaking.

How often should I clean my hot tub filter?

Hot tub filters need to be cleaned fairly regularly; especially if you want to get a full 2 ​​years out of your usage.

So imagine it like this. The more you clean and care for them, the less often you’ll need to replace them. Of course, if you’d rather not mess around with lots of cleanings, then just plan on getting new ones every year.

Here is what I recommend to keep these filters in good condition:

Monthly cleaning – 1 or 2 times a month

The recommended weekly cleaning is done by simply spraying down the filter(s).

Gently unfold the folds and remove all the dirt that has built up with water from your garden hose. If you want to prevent a mess, consider placing the filter in a 5-gallon bucket.

This allows you to throw away the dirty water when you’re done hosing down the filter.

Quarterly cleaning – every 3 to 6 months

If you intend to use the same filter for more than a year, you should think about a deep cleaning. Here is the process:

Use a 5-gallon bucket (like the orange ones at Home Depot) or even a new trash can large enough to cover the entire filter. Mix up your solution – Use a treatment that requires ½ part water and ½ part solution. This usually takes around 8 hours but check the label of the specific product you are using. Final Rinse – Quick rinse with water afterwards Let it dry – I know it sounds weird to let something dry before putting it in water. But that is exactly what is recommended. Place it back into the spa filter assembly

Of course, at some point you will need to replace your filters (which I just did).

How often do you need to replace them? Well, there is a range of 1 to 2 years. In a recent article, I detail why there is so much choice. But I also cover how to know when yours need replacing.

Can you use bleach to clean hot tub filters?

Many pool and spa owners try to use bleach as a sanitizer for the water, as well as a cleaning solution when the filters become dirty.

Bleach cleans clothes and other surfaces, so why not use it on filters?

Unfortunately not recommended. Here are two of the top reasons you shouldn’t use bleach in a hot tub or pool filter.

1. Bleach contains chlorine

Bleach, in particular, contains about 5% to 6% chlorine. Chlorine is incredibly powerful and can damage the pleats and ribbons around your hot tub filter very quickly.

It can also damage the filter unit if you don’t wash it off completely. Bleach also dries quickly, which is another enemy of hot tub filters.

2. Bleach dissolves too quickly

Even if you wanted to use bleach to clean a spa filter, it wouldn’t sit around long enough to do anything other than dry and crack your filter.

It’s an all-around bad idea in almost every scenario, so do your best to avoid this method.

If you want to use bleach to clean your filters, you’ll need to dilute it quite a bit. Direct contact of bleach to a filter is a big problem.

And while dilution might help lessen the effects, it’s still not a good idea. You should stick to products and solutions intended only for use with hot tub filters for best results.

While you can’t use bleach on your filters, there are other ways bleach can help keep your hot tub hygienic!

In a recent article, I broke down all the pros and cons of using liquid bleach to keep your hot tub safe and sanitized. I even detail the amazing way I use Mr. Clean Magic Erasers in my hot tub!

Final Thoughts

Here are the key points covered in this post:

You should not clean whirlpool filters in the dishwasher. While it may seem like an easy fix, it can damage your filters and may not even clean them properly.

While it may seem like an easy fix, it can damage your filters and may not even clean them properly. You should also not put whirlpool filters in the washing machine. Not only does the washing machine clean the filters poorly, but the filters can also damage the machine.

Not only does the washing machine clean the filters poorly, but the filters can also damage the machine. Proper cleaning of hot tub filters requires three tools: a hose, filter cleaning solution, and a hose attachment for evenly distributing the water. If you want to know the exact process, scroll up to the proper filter cleaning section.

If you want to know the exact process, scroll up to the proper filter cleaning section. You should not use bleach to clean spa filters. The chlorine in bleach can damage your filters, and the bleach usually evaporates before it can clean them.

Of course, filters aren’t the only thing that needs to be changed in hot tubs.

The water needs to be changed every 3-6 months depending on how often you use it. Not sure how to determine how often to change it? Confused about how to do it?

Filter Cartridge Cleaning Process 1. Remove the cartridge from the filter housing according to the manufacturer’s instructions. 2. Use a straight jet garden hose to rinse the filter element. Working bottom down, holding the nozzle at a 45 degree angle, wash any creases with emphasis between creases. 3. Flush until all dirt and debris is gone. 4. All spa cartridges and elements used in pools where sweat, sunscreen, and other oils are present, soak the element in (1) a filter cleaner for at least one hour (overnight is most effective); or (2) one cup of trisodium phosphate (tsp) to five gallons of water. 5. Rinse the cartridge again to remove oils and cleaning solution. 6. If the filter has a coating of algae, calcium carbonate (residual calcium hypochlorite), iron, or other minerals, immerse the cartridge in a solution of 1 part hydrochloric acid to 20 parts water until bubbles stop bubbling. *WARNING: Failure to remove all oils and cleaning solutions prior to acid soak will result in permanent water flow restriction and premature cartridge failure. 7. Flush cartridge clean and reassemble housing. Please note: Unicel does not recommend the use of Diatomaceous Earth (DE) with cartridge filters. DE particles can become trapped in the body of media and shorten cartridge life. If desired, a cellulosic fiber (synthetic DE) can be used in moderation. Baquacil as a disinfectant If you use Baquacil as a disinfectant, the filter element must be cleaned with Baqua Clean before using a cleaning agent. Unlike chlorine, which oxidizes the bacteria in the water, the active ingredient in Baquacil, polyhexamethylene biqunaid, or PHMB, destroys the bacterial cells. PHMB localizes and binds to bacterial surfaces and then attacks the outer bacterial wall. Once this wall has been compromised, the inner cell membrane or cytoplasmic membrane is destroyed. This destruction allows the cell contents to disperse to its environment, where it is further broken down into its elemental components by Baqua Shock, a non-chlorine oxidizer. In addition, Baquacil is a mild coagulant that binds bacterial cells and other small particles in the environment into particles large enough to be caught by the filter. The resulting deposit is a gray sticky film on the media that can only be removed with Baqua Clean. If trisodium phosphate (TSP) or any TSP type cleaner is used prior to stripping the film, the cleaner and the gray film combine to form a gummy substance. As soon as this occurs, the substance can no longer be removed from the medium and the filter cartridge must be replaced. WARNING: Follow all manufacturer instructions, warnings and precautions when using Baquacil, Baqua Shocks and/or Baqua Clean.

Spa filters are the kidneys of your spa water, removing impurities and particles to keep the systems working. Running your spa without a filter will quickly degrade the water quality, even in an indoor spa.

And that’s exactly why you’re here looking for solutions to your pesky hot tub filter problems and related water quality issues. So without further ado; Here are the most common spa filter problems and what to do about them.

dirty spa filters

A dirty filter might not be a bad thing if it doesn’t affect filter capacity or even dirt distribution or the amount of time between cleanings. Metals like iron can stain a filter with a light brown orange stain. Your filter may look gray, green, yellow, or even purple at times.

For spa filter stains that do not hose off easily, it is best to give the filter a thorough cleaning in a good spa filter cleaner. This will remove oils and minerals and most metal stains from the spa filter cartridges. Never use acids, bleach or other cleaning products that contain soapy phosphates; You’ll never find out and your tub will foam.

If some stains remain after soaking and rinsing, these may not affect the performance of the filter cartridge, but depending on their thickness, severe stains can reduce the microscopic pore size of the filter to the point where areas of the cartridge are unused.

The better question might be – what fouls the cartridge? Is it in the water like metals or algae, or a by-product of certain chemical combinations? Are calcium hardness and pH high? Do you need to pre-filter your fill water?

Holes in spa filters

Back when I was making a living servicing hot tubs, I was cleaning a filter cartridge and noticed it had stitches. The lady of the house told me very proudly that she had “stitched” them together! OK, but for the rest of us, a spare cartridge is fine if holes are noticed. Even very small holes reduce your filter effect.

The better question might be – what caused holes in the cartridge? In this case, the lady of the house had, unbeknownst to her, installed a large pool pump on top of a small spa filter. It had blasted pencil sized holes in the spa filter cartridge. I’ve also heard stories of certain insects taking a liking to spun polyester, so stock your spares accordingly.

cracked spa filters

When you say a cracked spa filter, what is usually meant is that one of the colored rubber end caps has developed a split or tear. Spa filters can also break across the central support cage. Both cases are rare, but if your spa filter has a crack in one end (not tiny hairline cracks, but actual cracks) you will need to replace the cartridge.

Perhaps the better question is – what caused the end cap to break in the first place? Could be the same as spa filter holes, a crack in the end cap could be from a spa filter pump that is too big for the filter size. Cracks or holes can also occur if a valve downstream of the filter is closed while the pump is running, or in some cases when an undersized filter is extremely dirty.

Fuzzy spa filter

Are the tips of your pleated fabric smooth and relatively free of fur? In some cases, spa filters can become fuzzy at the pleats and this can reduce your filter’s ability to trap dirt by reducing the spacing between the pleats. It also creates a lot of turbulence for water and debris as it enters the folds (on a small scale).

Why does the spa filter cartridge seem to be dissolving around the edges? This is usually due to chemical problems in the spa, poor water balance, or high sanitizer levels. It is also caused by cleaning the cartridge with too much water pressure. A new spa filter is fine.

Clogging spa filters

Is your spa filter clogged again a few days after cleaning? This will not work, in most cases expect a 2-4 week filtration cycle depending on the size of the filter cartridge and spa usage and to some extent water balance as mentioned above.

A filter that clogs quickly is likely to be coated with mineral deposits, oil films, or both. Cleaning with spa filter cleaner is designed to unclog the microscopic passages between the fibers of the filter. TSP can also be used on oily filters, but it will not remove mineral deposits from hard water.

If your filter is still clogging quickly after cleaning, it’s probably best to replace it, even if it’s relatively new. Provided it is properly sized for the pump and properly installed, the filter cartridge quickly loses its lifespan as it cleans certain substances from the spa water.

The better question is: what vegetable, oil or mineral is clogging the spa filter?

Hot tub filter cartridges naturally degrade over time, the woven fibers separate and they are unable to filter the smaller particles. Or filter cartridges are covered with difficult-to-remove oily and encrusted deposits and quickly become clogged. Replace your spa filter every 12-24 months.

A few things not to do – don’t put your spa filter in the dishwasher or use a pressure washer to clean it. Simply hose off, soak in one of our many spa filter cleaners and rinse clean again.

If you are considering getting a hot tub, or if you have recently purchased a spa, chances are you have many questions about how they work, when to use them, and if there are some important things you need to know about owning a hot tub and Maintenance. By getting a hot tub, you’re breaking new ground (pun intended!).

Even if you’ve owned or are friends with hot tubs before, there are always some questions you need answers to, such as how to care for your hot tub, water chemistry, maintenance and more. Some even question whether hot tubs are expensive to run. The main thing… there are no stupid questions.

One of the most common questions our team is asked is, “Should I leave my hot tub on all the time?” Quite simply, the answer is yes…your hot tub is designed to stay on all the time and works best , if it stays on all the time. Your hot tub is most efficient when it runs 24/7.

Why is it better to keep the hot tub going?

Some customers want to know whether they should use a hot tub in the winter or turn it off…this obviously depends on each family’s individual circumstances, but we think winter is the best time to own a hot tub! They also want to know why it’s best to keep their hot tub running all the time.

1. It’s cheaper!

One of the main reasons for leaving your hot tub on all the time is… the cost! Once your hot tub has reached the desired temperature, it only requires a relatively small amount of electricity to keep the water at that temperature. In the summer this is very common as long as your hot tub is well insulated and the cover is in good condition and is airtight around the hot tub surface.

Of course, the ambient temperature will be much colder in winter, so the hot tub’s heating system will have to work harder to keep the water at your chosen temperature. That being said, if you turn the hot tub off and on regularly, it will take hours and hours to heat up again, which you will definitely notice on your electricity bill!

How to clean a pool filter

The filter in your swimming pool catches and removes dirt and debris, hair and dead insects. It even removes finer particles like bacteria, sunscreen and body oils. Over time, the pleats in the filter become clogged, preventing water from flowing through and increasing the pressure in the filter. The higher the pressure, the less volume of water your pump can move as it works harder. The harder your pump has to work, the shorter its lifespan.

The filter not only keeps the pool water clean, but also ensures that the pool chemicals are evenly distributed. Your hard-working filter needs the same attention you give to the rest of your pool to keep it running longer and more efficiently. This in turn saves you money, energy and time.

There are three types of filter systems: D.E. (diatomaceous earth), sand and cartridge. EN Filters are the most efficient as they can capture particles as small as 3-5 microns. To put that in perspective, the smallest the naked eye can see is 35 microns.

Many DIYers use trisodium phosphate (TSP) and muriatic acid to clean their pool filters. Both TSP and hydrochloric acid are toxic and require wearing protective rubber gloves, goggles, and a mask when cleaning.

Simple Green All Purpose Cleaner is harsh on heavy soiling and greasy residue, yet gentle enough to clean filters without damaging the material. The biodegradable* formula leaves no harmful residue to circulate into your pool water.

It is best to clean your filter once a month during the summer and every two months during the winter (if you are still operating your pool).

Can you use vinegar to clean your hot tub or spa?

You can use vinegar or any other acetic acid to clean your hot tub, but we recommend our pH Down for best results.

Vinegar is an all-purpose cleaner. From the floors of your home to your favorite coffee mugs, vinegar can fill almost any cleaning need. So it makes perfect sense that vinegar would also be effective for cleaning your hot tub.

Why do you need to clean your hot tub?

Water quality in the Midwest isn’t always good. Due to the location in predominantly inland areas, the water has a higher lime content. In your hot tub, this results in a film that can cover your device’s case. The limescale will not harm you, but the buildup can appear unsightly.

Why Use Vinegar?

Vinegar does not contain any harmful chemicals. It cleans and deodorizes and is naturally safe around people and pets. Vinegar can help prevent clogs in your hot tub jets, eliminate bacteria, and remove water stains and other debris.

Are there alternatives to vinegar?

Diluted white vinegar is great, but you can also use lemon juice, CLR, or other similar acetic acid solutions to help remove and dissolved limescale. You could even use muriatic acid, but be careful.

At Royal Spa we prefer to use acid-based pH Down. Simply add a capful of pH Down to your hot tub water at night and let it circulate while you sleep. The acid in the solution breaks down any limescale that leaves the tub via the unit’s filtration system.

You can then return the next day with a terry towel and wipe down the hot tub to remove any remaining debris.

If you want one thing in your hot tub, it’s clean water. This is where your hot tub’s filtration system comes into play.

This system circulates the water through your spa and removes any impurities in the water. Combined with the chemicals or other sanitizers you use in your hot tub, the water is purified so you can enjoy a comfortable soak that not only feels good, but is safe.

But how does this system actually work? Let’s take a closer look at how a hot tub’s filtration system works so that you can understand what your hot tub is doing day in and day out.

filter system

Every hot tub uses a filter to remove dirt and other debris in the water. How you approach this task depends mainly on the type of filter used.

suction type

The suction filter is the most common type of filter used in hot tubs today. These systems are always top mounted for easy access. They are often much larger than the other types of filters and much easier to maintain. However, you need to maintain them regularly for them to be effective.

print type

Pressure filters are not the most common, but are still used in some spas today and are often found on older hot tubs. With this system, the filter cartridge is often smaller and housed in a sealed canister, with the skimmer housed in its own separate unit. These systems can handle much more pressure and don’t need to be serviced as often. However, maintenance tends to be more difficult when you have to work on it.

Which one is better?

Don’t look at it positively or negatively. The fact is, they’re both very different, but they’re basically doing the same job, and they’re both good at it. All you have to do is figure out which one you’d rather work on. Do you want the filter that’s easier to service but needs more frequent maintenance, or the filter that’s harder to work on but needs less maintenance? Really, in the end it all comes down to you.

filtration cycles

A filter cycle is the amount of water that passes through your spa filter. Every hot tub is different and you may have some control over it. However, this is the true test of the quality of your hot tub. The more water you can pump through the filter system, the cleaner it will be.

circulation pumps

A circulation pump is different from the main pump and jets in your spa. It is basically a secondary pump that runs continuously to pump smaller amounts of water through the filtration system. These run even when your main system is shut down. Although you cannot use them alone, they are a great way to keep the water clean as they prevent water from standing in your hot tub.

control system

While the above illustrates the main parts of the filtration system, don’t forget the control system. This system is typically controlled from a control panel on your hot tub. From this control panel you can access the many functions of your spa and control the filtration system.

Depending on the type of spa you have, your ability to control the filtration system will vary. In some cases, you can control the flow of water and adjust how much water is regularly filtered in your hot tub. In other cases, you can choose different presets, all based on the number of bathers in your hot tub.

Get to know this system well so you can properly control your hot tub, and be prepared to adjust the filtration system with heavier bathers to ensure the water stays clean.

So how does it work?

It’s quite simple when you think about it. Your jets and pump push the water through the spa filter to remove any particles in the water. The more water that can be pumped through the filter system in one cycle, the cleaner it is. These cycles often run periodically throughout the day based on your bath load. Make sense?

Final Thoughts

Your hot tub’s filtration system is your primary defense against dirt and other debris that may contaminate your hot tub’s water. That is why it is so important to take care of it. After all, you don’t want to bathe in dirty water, do you?

While the system itself is fairly simple, in many ways it is the mainstay of your system. Without them, your hot tub is simply not safe to use. Now that you know and understand the basics of this system, you’ll be better able to take care of it properly so you never have to worry about dirty water again.

Hot tubs are a great way to wash away the stress of a long day – until the hot tub itself needs washing. A dirty hot tub means bad odors and dirt. The worst part? Cleaning supplies filled with chemicals that are harmful to your family and the environment. Luckily, natural cleaning agents like vinegar are just as effective in getting that squeaky clean clean you crave.

To clean your hot tub, start by adding a gallon of vinegar to your water and letting it run through the plumbing for at least two hours. This attacks the biofilm in the pipes and nozzles. Next, make a 1:1 solution of vinegar and water to wipe down your bathtub cover and tray.

Vinegar is a cheap and natural solution to dirt and bacteria that you can easily find at your local grocery store. Not only that – it is so versatile that it can be used to clean all parts of your hot tub. Learning how to use vinegar to your advantage will make the otherwise stressful and time-consuming task of cleaning your hot tub easier.

How to clean a hot tub with vinegar

As you now know, not only is vinegar a great addition to your salad dressings and steak marinades — you can also use it as a safe and environmentally friendly hot tub cleaner. To use vinegar to thoroughly and properly clean your hot tub, you should focus on cleaning these five main areas:

lines and pipes

water jets

inner shell

bathtub cover

filter

These components are essential to the function and longevity of your spa. Although the task can seem daunting, you should drain and clean your tub every few months to prevent a build-up of dirt and bacteria. The good news is that vinegar can be used in all parts of the cleaning process, making the task easy and effective.

But wait! Before draining your tub for cleaning, first flush your plumbing. Biofilm, or bacteria, builds up in your spa tubing over time. Too much biofilm can not only cause cloudy water and reduced jet pressure, it can even make you ill. Pour a gallon of white distilled vinegar into your tub and let it run for a few hours or overnight to get rid of this mess.

Once you’ve flushed your lines and drained your tub, you can focus on surface cleaning. Follow these five simple steps to a sparkling clean hot tub:

Step 1: Create your cleaning solution. You will need to mix vinegar and water in a 1:1 ratio in a spray bottle. Shake or stir the solution well to ensure it is evenly mixed before use.

Step 2: Spray the inside of your spa bowl in sections, letting it sit for at least 15 minutes at a time to allow it to attack mold, algae and bacteria. Focus on nooks and crannies for a thorough clean, then wipe with a soft cloth. Rinse well and drain.

Step 3: Aim for your jets. Although most nozzle-blocking debris and bacteria will be flushed away when you flush your lines, bacteria can easily get trapped under the nozzle caps. Spray nozzle covers with the same solution and wipe with a soft cloth or brush. Remove the caps and use the same tools to clean the underside.

Step 4: Now it’s time to clean your hot tub’s filters. Filters remove dirt and bacteria from the water, so they themselves need to be cleaned thoroughly to continue to function effectively. Using a large bowl and the same vinegar solution, soak your filters for at least two hours, then rinse thoroughly.

Step 5: Don’t forget your hot tub cover which can harbor bacteria and debris when braving the elements. Spray down your cover and let your vinegar solution sit for 15 minutes before wiping your cover down with a soft cloth and rinsing well.

What Kind of Vinegar Should I Use?

Cleaning your hot tub with vinegar is both effective and safe – but what type of vinegar is best? With so many different types on the market, it can be difficult to determine which is the most effective. For this reason, it’s important to choose your vinegar wisely when deciding to clean your hot tub.

White distilled vinegar is our top choice because it has an acidity of around 5 percent. It’s also made up of acetic acid (the source of its acidic smell and taste), which is also found in other store-bought cleaning products. This means it easily cuts through dirt, bacteria and stains in your hot tub, yet is gentle.

White vinegar is uncolored, so it won’t stain light-colored surfaces or materials like balsamic vinegar or red vinegar. This is especially important when cleaning your hot tub cover.

Unfortunately, with all the benefits of cleaning with vinegar, there is also a downside: the abrasive smell. Can’t stand the smell but still want to use vinegar as a hot tub cleaner? Be sure to air your tub well after cleaning and before filling to dissipate the odor. You can even add a few drops of essential oils to the solution to naturally curb odor.

How often should I clean my hot tub?

Now that you know how to clean your hot tub with vinegar, you may be wondering how often it is necessary. This depends a lot on how often you use your tub, but it’s a good idea to have regular maintenance regardless of usage.

Every few days you should visually inspect your hot tub for signs of water cloudiness or discoloration. It’s also important to check chemical levels regularly with test strips to make sure the pH is balanced and that bacteria killers like chlorine are at safe levels.

Every month you should clean your filters as their primary function for your hot tub is to maintain a dirt and bacteria-free environment. When your filters get too dirty, they can no longer successfully capture harmful chemicals and debris that can endanger your spa – and you. Scrub your hot tub cover once a month as well.

Major maintenance, like draining and cleaning your tub completely, should be done every four to six months. If you use your hot tub twice a week or more often, you should aim for every four months. If you only use your hot tub a few times a month, aim for every 6 months.

summary

A hot tub is a great way to relax and unwind, but it’s also an investment that requires frequent maintenance and cleaning. Many store-bought cleaning products are chock-full of harsh chemicals that are potentially harmful to pets or children, and particularly bad for the environment. Thankfully, vinegar is the perfect natural solution to your cleaning needs.

Using vinegar to clean your hot tub is not only effective, but also safe and easy. The high acidity cuts through most debris, meaning it’s your one-stop shop for hot tub cleaning bliss. Vinegar is a cheap, antibacterial, and environmentally friendly way to ensure your hot tub is running safely and effectively. All you have to do is sit back and enjoy.

Did you know that while hot tubs and hot tubs are similar and both require cleaning, there are some differences? You can find out the differences between these products here.

The filtration system is an integral part of the spa. Bathers bring a lot of dirt into the hot tub water, such as dirt, sweat, hair, etc.

Filter cartridges act like a sieve, removing dirt as the water passes through. Regular cleaning and replacement of the filter allows the filtration system to better remove dirt and oils. This means improved water clarity and longer spa equipment life.

When replacing, choose high-quality, long-lasting filter cartridges. Although many cartridges look the same, inferior filters often need to be replaced to avoid clogging and spa inefficiency. Clarathon Premium Ultra Filters last 1 year – 4 times longer than the cheap 90 day life of other competitors.

Rinse bi-weekly to remove dirt

Filter cartridges should be rinsed every two weeks to remove larger particles such as leaves and hair. Heavy use may require more frequent rinsing.

Remove the filter cartridges by following the spa manufacturer’s instructions for removing the filter. Clean with a filter spray nozzle at a 45 degree angle between the pleats to remove dirt deep inside the filter. Replace a standard garden hose sprayer if you don’t have a filter cleaning sprayer.

Easier cleaning with filter products and tools

Save time and energy on your filter maintenance schedule by adding some great products and tools like spray nozzles and cleaners. A small investment makes a big difference in your hot tub’s filtration capability.

ecoTUB instant filter spray combined with a filter spray hose attachment cleans quickly to remove oily buildup and dirt without the need for a soak.

Various hose end filter cleaning tools are available that are superior to standard hose sprayers. They spray water deep into the folds, resulting in cleaner filters and less work.

Our favorite atomizer is the Jet Stream filter cartridge cleaner. The Jet Stream includes two tools: an outer fan sprayer with nozzles to get deep into the folds, and a core cleaning tool that also cleans the inside of the filter.

Another great tool, the Blaster Automatic Filter Cleaner also connects to a standard garden hose and rotates the filter while cleaning for a hands-free method.

Never clean the filters with pressure washers, dishwashers or scrubbing brushes. High pressure, boiling water, and brushing can wrinkle end caps, break ligaments, or weaken the filter.

Soak and rotate quarterly with clean, dry spares

While rinsing removes dirt, filters can become clogged with body oils, lotions, soaps, and mineral buildup, necessitating a routine deep cleaning.

Replace dirty filters with a clean, dry set at every water change and at least every 3-4 months. Rotating filters mean you never have to wait until you’ve cleaned your filters to use the hot tub.

Rinse dirty filters thoroughly as soon as they are removed from the spa. After drying, deposits are more difficult to remove.

Mix filter cleaners like Power Soak or ecoTUB Filter Soak in a bucket of water and soak the filters overnight. Using hot water when soaking the filters can greatly speed up the filter cleaning process.

Remove the filters from the bucket, rinse again to remove residue, then dry in a clean place. Drying the filters will help control any mold or microbial growth that may persist on wet filters. Our blue antimicrobial filter cartridges prevent the growth of odor and stain-causing microbes on the filter media.

Note: Antimicrobial filters do not sanitize the spa water itself. Use a disinfection system such as Bromine or Nature 2.

Do not use anything other than filter cleaner to clean the filters. Dichlor, laundry bleach and other forms of chlorine in high concentrations can damage filters and lead to premature failure.

Detergents, soaps, and other household cleaners leave residue in the filter, which also causes foaming and water problems.

For spa owners with hard water, limescale can restrict the flow of the filter cartridge. After cleaning, soak the filters in a solution of 20 parts water and 1 part Acid Magic until the bubbling stops. Acid Magic is safer than muriatic acid but just as effective at removing scale.

If you use disposable micro filters, you don’t have to soak them every 3-4 months. Flush every two weeks to remove larger debris, then discard the filters with every water change.

Replace annually for optimal efficiency

Although cleaning improves the filtering ability of the cartridge, eventually the filter media ages and can no longer function as efficiently. To avoid stressing spa equipment and reducing water clarity, we recommend yearly replacement. Heavy usage spas and commercial settings will require more frequent filter changes.

Since filters are always filtering dirt and are exposed to spa chemicals, poor conditions can cause them to fail prematurely. Fortunately, there are signs that a filter will age and no longer perform as well as a new cartridge.

Fabric filter media becomes fuzzy, frayed, or torn

Broken, loose or missing bands if the filter is banded

Faded, brittle or cracked end caps

Wrinkles that stick together or collapse even after cleaning

Pleats separate from the end caps

Stains and odors that remain after cleaning

If your filters need to be replaced frequently, check spa conditions to ensure you are getting the most out of the filter. Showering before entering, regular balance and disinfection checks, and frequent filter cleanings are the best ways to extend filter life.

Additionally, using a water filter at the end of the hose removes contaminants from the water as the spa fills. This reduces the workload of the filter system.

Floating foam and oil removers – like the Zorbo – also reduce the material that flows through the filter.

Keeping your hot tub clean is not only a way to ensure an enjoyable bathing experience, it is also important to the ongoing maintenance and smooth running of your hot tub. One of the most important aspects of keeping a hot tub clean is taking care of your hot tub filter through regular cleaning and regular replacement. Keeping a spa filter clean can have benefits you might not have expected, including better efficiency, less chemical use and more jet power! This blog post will help you understand what a hot tub filter is, what it does, why it’s important to keep it clean, how to clean a filter, and some useful tips and advice.

What is a hot tub filter? How does it work?

A hot tub is designed to filter and heat by circulation. Dirty water flows through the filter and/or is sucked in by the pump or circulation pump, then flows through the heater and is pumped out again through the nozzles. This circulation process provides clean, warm water and hydrotherapy – the entire foundation of a hot tub. The filter plays a key role in this process as it ensures that the water returning through the pump and heater is clean and free of debris. He is also level 1 in the circulation process, which means that any kind of problem here will cause more problems down the line. Problems with dirty filters are explained below.

Hot tub filters are typically made from a pleated polyester media. This medium filters the water and catches dirt along the way. Manufacturers have used innovation to improve filter media over time. An example is the patented Hot Spring Tr-X filter, which is made of ceramic fiber, making it more durable, longer lasting and more efficient.

Why is it important to keep a hot tub filter clean?

As discussed above, a hot tub filter is fundamental to the functioning of a hot tub and when dirty it can cause the following problems:

Low flow – this can be highlighted by an error message on the screen such as “—” or “FLO” or “DRY”. Here the sensors do not detect enough flow through the heater, so the heater is switched off for safety reasons. Low flow can also cause stress on the pump, slower heating and less output from the nozzles.

Dirty water. The filter plays a key role alongside your sanitizer (chlorine or bromine) in keeping your hot tub clean. When a filter becomes clogged or dirty, it can affect the clarity and cleanliness of the water and also lead to inefficient disinfection (with lots of chlorine or bromine).

load parts. When a filter becomes extremely dirty, debris can get into the heater, pumps, sensors and other vital working parts of the spa. This can cause parts to become faulty.

How Long Should Hot Tub Filters Last?

Hot tub filters should last a minimum of 1 year and generally a maximum of 2 years. If a filter is maintained and cleaned regularly, it will last longer. Ceramic spa filters like Hot Spring’s Tr-X filters can last up to 5 years due to the durability of the ceramic design. A spa filter needs to be replaced when the media material begins to break down. At this point, filtration becomes ineffective and a fresh filter will help save money, protect your spa’s working parts, and improve flow. A great way to extend the life of hot tub filters is to have a spare filter and swap out filters regularly to allow time for a thorough cleaning and consistent filtration. Check out our range of quality replacement filters.

How to clean hot tub filters

Option 1 – Quick Rinse

This option is the quickest way to clean your filter and is recommended as a weekly process. It’s not a deep clean, it’s a quick rinse to remove large residue. This will not remove any grease or oil from your filter, so it is not recommended for a heavily soiled filter. If your filter is heavily soiled see option 2 or 3. To make rinsing your filter easier and more thorough check out our Super Blaster filter cleaning tool.

Turn off your spa at the circuit breaker. Remove your filter. Use your hose to flush up and down and in the folds. If you have time, let your filter dry before putting it back into your spa.

Option 2 – Instant filter cleaning spray

A more thorough option than just a quick rinse and recommended as a monthly or bi-weekly procedure depending on spa usage. Instant Filter Cleaner is a great degreaser and removes oils from your filter.

Turn off your spa at the circuit breaker. Remove your filter. Rinse your filter quickly to remove large debris. Thoroughly spray the surface of the filter with Happy Hot Tubs Instant Filter Cleaner to impregnate the filter, wear protective clothing (gloves and eye protection, etc.). Leave the filter for 10 to 15 minutes. Gentle use of a soft brush or Happy Hot Tubs Super Blaster can help lift debris. Heavily soiled filters may need a second treatment or soak treatment. Rinse thoroughly before placing the filter back in your spa. If you don’t rinse thoroughly, foaming will occur. If you have time, let your filter dry before putting it back into your spa.

Option 3 – Soak Filter

This option is the slowest cleaning process, but arguably the most thorough, as a degreasing solution is allowed to soak into the pleats of the filter over a period of time. Because the process is slower, it goes well with your water drain and refill every 3-4 months. Some hot tub owners follow this process monthly when they swap out a clean and dry filter, giving them time to soak and clean the dirty filter.

Turn off your spa at the circuit breaker. Remove your filter. Rinse your filter quickly to remove large debris. Add a filter soaking solution such as Happy Filter Cleaner, Immerse Filter Cleaner or AquaSparkle Cartridge Cleaner to a bucket according to the correct dosage on the bottle. Let the filter soak for at least 8 hours. Rinse thoroughly before putting the filter back into your spa. If you don’t rinse thoroughly, foaming will occur. If you have time, let your filter dry before putting it back into your spa.

frequently asked Questions

Can I use my dishwasher to clean my spa filters?

You cannot use your dishwasher for regular polyester mesh filters as this may damage the media. If you have Hot Spring Tri-X ceramic filters, you can wash your filters in a simple rinse cycle in the dishwasher.

Why is it best to dry a hot tub filter before putting it back in?

By drying a filter, you reset the fibers and make the filter more effective. It’s fine to run a filter wet or dry, but dry tends to provide more effective filtration for a period of time.

Can I run my hot tub without a filter?

no If you do this, you increase the risk of dirt and other objects getting into the plumbing and damaging your hot tub. It is best to turn off your hot tub when you remove your filter.

How often should I clean my hot tub filter?

This depends on usage, but you should visually inspect your hot tub filter at least weekly. If you feel it needs flushing, you should quickly flush it with the hose at this point. You should clean your filter more thoroughly monthly.

If you live in the southern United States, chances are you’ll find solace in your pool during the warmer months of the year. Some days it seems like the only way to enjoy the outdoors is to spend the day cooling off in the backyard pool at your home.

Yet as much as we use our backyard pools, it’s easy to take them for granted. Especially in the summer months, we want to be sure that our pools are clean and ready for use at all times. While it’s safe to assume that the pool’s filter keeps it clean, many homeowners overlook the fact that the filter itself needs to be cleaned regularly.

How to clean pool cartridge filters

In this post, we’ll discuss the types of filters you might be using in your pool, how they work, and how and when you should clean your filters. Read on to learn the ins and outs of cleaning your filter and everything you need to know beforehand.

Pool Filter Basics

Before cleaning your pool filter, it’s important to understand why it’s important, what its function is, and how it works. A pool filter is simply a device that filters or separates the water from dirt and other particles to keep your pool clean. Think of it like a colander: water is filtered through the holes while the larger pieces of pasta stay in the colander.

Most filters consist of cartridges made of non-woven polyester spunbond fabric that forms a tight mesh that water can pass through but dirt cannot. This keeps your pool water clean. However, over time, the dirt trapped within begins to build up on the fabric. Once this occurs, the material loses its ability to properly filter the water or separate the dirt from the water. When this becomes obvious, it’s time to clean your filter.

Types of pool filters

There are three types of pool filters available: sand, cartridge and diatomaceous earth or D.E. Filter. The main differences between the three are the filter media that reside in the tank that each uses. Regardless of the type of filter, they all need regular cleaning. Let’s discuss both in detail.

sand filter

Sand filters are incredibly common among homeowners as they are typically the easiest of the three filters to use. In a sand filter, pool water is pumped into the filter where dirt and unwanted materials are trapped in the sand. The sand is tightly compacted, so the design makes it difficult for water to get through, but dirt even more so.

Although it may seem counterintuitive, sand filters actually work more efficiently when they are lightly soiled. That’s because small particles left behind reinforce the densely packed materials. For this reason, sand filters should only be thoroughly cleaned when the homeowner notices an increase in pressure or when the filter’s pressure gauge shows a 7-10 pound increase over the normal operating pressure. However, it should be backwashed a few times between thorough cleanings. A good sand filter cleaning schedule is at least every season.

However, replacing the sand in your sand filter is a little different. It is therefore best to consult your local pool professional to best determine the frequency of this.

When it comes time to backwash your sand filter, you should start by cleaning out the debris trapped by the sand. Be sure to turn off the pump before changing the position of the main valve. Otherwise you will probably break part of the filter. Once you have verified that the pump is off, move the lever to the backwash position to restart the pump. The pump starts to push the water through the filter; The water will turn clear, then dirty, then clear again to indicate the cycle is complete. After this operation, return the valve to its normal setting.

Remember that this process removes water from the pool. So be sure to check the water level before you start and do not start the cleaning process when the water level is already low.

cartridge filter

Of the three filters mentioned, cartridge filters have the highest capacity of all. In fact, these can capture twice as much dirt and debris as a sand filter. This is possible because it has a larger filtering area that allows water to move easily through the cartridge while still capturing smaller particles. Despite its larger size, a cartridge filter is much easier to maintain. It is also considered the most common and is usually located behind a gate or screen in the wall of your pool.

To clean a cartridge filter, you should allow adequate time to do it properly. First turn off the filter system and slowly let the air out of the filter by turning the bleed valve. Next, remove the clip holding your filter together and remove the top of your cartridge filter to see inside. Once you have removed everything holding the cartridge in place, take out the cartridge elements and inspect for damage. If the plastic is cracked or broken, it is strongly recommended that you purchase a new filter cartridge, as small cracks can significantly reduce a filter’s effectiveness.

After removing the cartridge, coat the parts with a filter cleaner and follow the product directions for how long to leave it on before rinsing it off. Then use a hose with an attachment to remove dirt and debris from between the folds of the cartridge.

After cleaning, put the cartridge elements back in and place them securely where they once were. Ensure that all cartridge elements are properly secured before powering on the system. After your system is up and running again, bleed excess air from the system by opening the bleed valve at the top of the filter canister until water constantly spurts out of the valve.

Cartridge filters are ideal for above ground pools and unlike the others, they can also be used in above ground pools.

EN filters

Diatomaceous earth filters differ from the other two options in that the D.E. is the filter medium itself, while the other two filters consist of different components. DE is an extremely fine powder or crushed rock composed “of chemically inert, fossilized remains of billions of microscopic algae-like organisms called diatoms.” Because D.E. Filters are more compact and can filter out smaller particles than the other two filters, they are considered the best choice for residential pool filters. However, the downside is that it is the most expensive type of filter available.

Although a backwash is only once or twice a year for D.E. Residential pool systems, keep an eye on the pressure gauge to ensure you clean or replace the system when necessary. When the gauge drops below eight pounds, it means it’s time to replace it.

Change or add new D.E. is actually easy to do. Simply the new D.E. into the skimmer and the pump sucks the D.E. in place. Remember that the biggest mistake people make when doing this is not adding enough powder.

Pool filter cleaner: homemade or bought?

You can buy pool filter cleaners, but some pool owners choose to make their own. One method is to fill a bucket with warm water deep enough to fully submerge the cartridge. Then add one cup of liquid dish soap or dish soap for every five gallons of water. Allow the filter to soak for between one and eight hours before removing and hose rinsing.

Another way to make your own pool filter cleaner is to mix up one cup of trisodium phosphate for every five gallons of warm water. Fill your container enough to submerge your filter. Allow your cartridge to soak for between one and eight hours before removing the filter and hosing it down with water from your hose.

Pool Cartridge Filter Cleaning Tool: What Do I Need for the Job?

Many pool owners use a garden hose to clean their pool filter cartridge, but there are tools that make it easier. Filter floss, pool filter rods and water rod cartridge cleaners all attach to your hose to direct water flow more precisely, making your filter even cleaner. Remember that while some water pressure is good, too much can damage the fibers of the filter, so avoid using a pressure washer to clean your cartridge.

If you want to take the guesswork out of cleaning your filter, you might want to consider an automatic filter cleaner. These devices rotate your filter and distribute jets of water in your cartridge. The design allows dirt and debris to fall out of the filter when sprayed with water. Automatic filter cleaners come in a variety of sizes and will clean most cartridges in just a few minutes.

Can I clean the pool filter cartridge with bleach?

To remove a stain from a garment, you can soak it in bleach. Does that mean you can soak your cartridge in bleach? Companies that sell pool chemicals discourage this because bleach can damage the fibers in your filters, thereby shortening the life of your filter.

Cartridge manufacturers offer a range of products to keep your filters clean. Some pool owners make cleaning solutions from detergents or vinegar, which are gentler on your filters over time.

How to clean the pool cartridge filter with algae coating

In some cases, you disassemble your pool filter cartridge and find that your filter is covered in algae. In these cases, you should soak the filter in a solution of 1 part hydrochloric acid to 20 parts water. When the bubbling stops, rinse the filter. If that doesn’t solve the problem, you may need to soak it with commercial filter cleaner or a solution of one cup of trisodium phosphate to five gallons of warm water.

Why are filters necessary?

While it may seem like an obvious task, cleaning your pool and realizing how important it is is often overlooked by homeowners. For starters, unkempt pools and filters can lead to more serious backyard problems down the road, ultimately making more homeowners more money.

A clean pool is also essential for the health of you and your family. The cleaner your pool water, the less likely it is to contain parasites, waterborne diseases and bacteria. The same applies to the environment. If your pool becomes dirty or contaminated, you run the risk of dirty water seeping into your neighborhood waterways and surrounding areas.

If you want a quick but clear preview of some of the things we’re about to talk about, you can watch this video – just keep in mind that details may vary by brand.

Why do you need to clean a hot tub filter?

Before we get into how to clean a hot tub filter, let’s look at a few questions such as: B. why you need to do this and how often.

A clean filter is one of the keys to ensuring your hot tub is running smoothly and correctly. A clean filter helps keep the water free of germs and debris, and makes tub maintenance easier. The same goes for inflatable hot tubs.

However, if the filter is not cleaned, the performance of the pumps decreases and it becomes more difficult to keep the water clean, even with chemicals. It can even affect the heater’s ability to maintain the right temperature.

How Often Should You Clean a Hot Tub Filter?

How often you need to clean the filter depends largely on how often you use the hot tub. It is recommended for most users to clean the filter about once a month, although you may need to do this more frequently with heavier use.

As a general rule, you should check the filter every two weeks, lightly clean it monthly, and deep clean it every two to three months. So you can be sure that your filter is always in perfect condition.

Some more advanced tubs also have a built-in alert system that notifies you if there is a problem with the filter – for example, if it needs cleaning or is clogged. For more details about your model, see the user manual.

What do you need?

You don’t need a lot of specialized equipment to clean a hot tub filter, but there are a few things you should prepare beforehand. These include:

garden hose

Large bucket (large enough to fully submerge the filter)

Filter cleaning liquid

Hand towel

Steps to cleaning a hot tub filter

Cleaning the hot tub filters is very easy and doesn’t take much time. Here’s a step-by-step guide on how to do it.

Turn off the power

The first step is to turn off the power to your hot tub. Running your hot tub while removing the filter can result in dirt and debris being sucked into the filter mount.

If your hot tub is hardwired, you will need to turn it off at the circuit breaker. If it’s a 110V version, all you have to do is unplug it.

Remove the filter

Find the compartment where the filter is located and open it. Most tubs only have one filter, but some models have two. If it’s still on, you’ll need to remove the spa’s cover to access the filter compartment.

To remove the filter, on many tubs, all you have to do is turn it counterclockwise to unscrew it, and then lift it out. However, since the filters in different tubs can be different, you should refer to your owner’s manual to find out how to do this on your model.

Check for damage

If you remove the filter before you start cleaning, you should check it for damage. This should be part of your bi-weekly check-up, even if you don’t plan on cleaning the filter. If you find that it is damaged, you must replace it as soon as possible.

Remove larger dirt by hand

Once you’re satisfied that the filter isn’t damaged, you can begin to remove larger debris caught in it by hand. This could be leaves or twigs that fell into the water and were sucked into the filter.

Spray the filter with the hose

After you have removed larger dirt particles, you must remove any smaller particles that have become lodged in the filter. To do this, take the hose and spray it off. Be careful not to use too strong a spray or you may damage the filter.

Thoroughly clean the filter

Next you need to soak the filter to remove smaller particles that have become trapped in it and to kill any bacteria that may have started to grow. You need a special filter cleaning agent for this.

Take the bucket and fill it with enough water to fully submerge the filter and add the detergent.

Since all cleaning products are slightly different, it’s a good idea to check the bottle and make sure you’re using the correct dose.

Place the water filter in the solution of water and cleaning liquid and let it soak, preferably overnight. Note that using hot water can speed up the process and you only need to let it soak for about an hour.

Rinse the filter

When the filter is soaked, you need to remove it from the bucket and rinse it thoroughly. Leaving some of the water and cleaning solution on the filter can cause foam to form in your tub when you use it again.

Replace the filter

When the filter is fully rinsed, you can put it back in the tub. Screw it in the same way you unscrewed it – or if your tub uses a different method, follow the instructions in the owner’s manual. Replace the cover when it is reinstalled.

Turn the power back on

Once the filter is reinserted and the compartment closed, you can turn your tub back on. Just flip the circuit breaker or plug it back in and you’re good to go.

Tips for cleaning a hot tub filter

Here are a few tips that might help you clean your filter.

You can use a spray for monthly cleaning

There are filter cleaning products that don’t require an overnight soak – instead, you just spray the filter and then rinse it off.

You can use one of these for monthly cleaning, but if you do, you should still soak the filter in a solution of water and detergent every two to three months.

Follow steps 1-5 for your bi-weekly cleansing regimen

For bi-weekly cleaning, you can only do steps 1-5.

Run the tub after cleaning the filter

After cleaning the filter, you should let the tub run for a while before jumping in yourself. This allows any residue that got into the water during cleaning to be filtered out.

frequently asked Questions

Here are some frequently asked questions about hot tub filters and how to clean them.

Can you clean a filter with vinegar?

If you don’t want to use a dedicated hot tub filter cleaning product, vinegar is a reasonable alternative. When you get to step 6, put a 50:50 solution of water and vinegar in the bucket and soak the filter in it overnight.

Vinegar is one of the most efficient alternative cleaning agents – although it’s still not as effective as a proper filter cleaner.

Can you use bleach to clean a filter?

Technically, yes you can. However, it’s not advisable as bleach is very aggressive to your filter, and it’s much better to use a dedicated product.

If you need to clean a filter and don’t have filter cleaner available, bleach can be used as a substitute – but you shouldn’t use it every time or you’ll shorten the life of the filter.

Can you clean a whirlpool filter in the dishwasher?

Although some people might suggest it’s possible, it’s best avoided. Because the pressure of the nozzles in the dishwasher can damage the filter. Even if it comes out fine once, you may not have luck the second or third time, and you will end up shortening the life of the filter.

Can you put a filter in the washing machine?

no The wash cycle is too vigorous for a sensitive spa filter.

How long should a filter last?

This question depends on a number of factors, including how often you use your hot tub and the hardness of your water.

Under normal circumstances, a filter lasts between two and three years. With lighter use, a longer service life is not excluded – however, with more intensive use or in areas with hard water, you may need to be prepared to change it once a year.

Simple but essential maintenance task

Keeping a spa filter clean and in good condition is not difficult, it is just a matter of regular reminder. As long as you stick to a fortnightly and monthly schedule and follow our steps, you should be able to keep your tub running perfectly with minimal effort.
