Large Hot Tub Filters? Trust The Answer

Do you know the make and model number/code of the actual filter? It is usually located on the filter housing (not the cartridge) itself.

Examples of brands: Sta-Rite, Pentair, Hayward, Jacuzzi . . .

Examples of models: Crystal Flow, Sherlock, Clearwater, Proclean, Posi-Flow, Star Clear, Swim Clear, Tri-Clops

Examples of model numbers: C-250, 70TX, TC300, 100, 75 (there are many of them)

If so, use the search box above to find as many makes, models and/or numbers as you can find on the filter housing.

Another option is to look for an alphanumeric model number in raised letters on the top and/or bottom of the cartridge itself. Unicels usually look like C-####, filter cartridges start with FC-#### and Pleatco cartridges start with NN###. When you find this model code, look for it in the box in the top right corner.

If they can both find your cartridge and you’re pressed for time, give us a call and we’d be happy to help.

To identify your filter cartridge you need to do the following:

Measure the outside diameter of the end cap. Use an exact measurement (+ or – 1/32 inch). Measure the top inside diameter. Use the exact measurement (+ or – 1/32 inch). Measure the bottom inside diameter. Use the exact measurement (+ or – 1/32 inch). The types are listed in the table below.

If you know the brand (or manufacturer name), you may be able to find the cartridge with the above information in the list of cartridges by manufacturer

Once upon a time, if you wanted a replacement spa or hot tub filter, you would go to your local spa store and buy or order a replacement filter cartridge. There was no choice of brands, they were all made by Unicel or Aladdin.

As the number of pools and spas using pleated filter cartridges in the US grew to over 5 million, other domestic manufacturers entered the ring, namely Filbur and Pleatco.

Spa filter cartridges are surprisingly easy to make, all you need is one machine to make neat folds in the fabric and roll it into a tube and a second machine to shape and stamp the end caps.

This has resulted in a large number of imported spa filters being offloaded on US shores in packed shipping containers. Upon arrival, they are shipped to major retailers such as Walmart and Home Depot, as well as other bulk retailers.

There are some important quality differences in these cartridges imported from Singapore. It starts with the fabric, which isn’t Reemay®, but something called Remay, as in “Quality Remay Construction.” This is really pissing me off, and I hope the DuPont legal department has a remedy against those using knockoff names.

According to Unicel sources, the fabric used in most imported hot tub filters is substandard; and “Low-end manufacturers use inferior spunbonded polyester to reduce cost, but there is a significant difference in cartridge performance”.

Let me give a personal opinion and excuse my French; The spa filters from Home Depot, Lowes, Walmart and others suck. And not just because they use something different than Reemay, but also because the fabric weight isn’t stated or even mentioned.

For spa filter cartridges, a 3 oz. Fabric weight (per square foot) is most appropriate, with 4 oz. Used in high flow systems or very large spas. What is the weight of the fabric used in the spa filters sold by Home Depot, Lowes, and Walmart? Nobody knows, it seems to be a closely guarded secret.

Below are some of the characteristics of Pleatco hot tub filters – compare that to the Pro-Line filters that just say “installs in seconds” – well.

Pleated High Performance Polyester Media – (100% Reemay)

Reinforced antimicrobial end caps

Extruded PVC center cores

Formed threads, no loose inserts

If you want to get the best performance from your hot tub filters, stick with an established and well-known brand like Unicel, Filbur, Pleatco or Aladdin. Don’t be fooled into buying a half price cartridge that doesn’t even last half as long and you’ll have a cleaner, healthier hot tub.

Believe me ~ I have used the Cheapo cartridges before and within two days the water is cloudy and within a week I had to clean the cartridge. After two months I threw it in the bin. A good spa filter from the above brands can last 2-3 times as long with less cleaning and better filtration.

The size of your filter model should be marked by the manufacturer or the installer must do so during installation, but this is not always the case. To determine the size of your filter, you can measure specific parts of the filter to determine its size. Measure the diameter of the tank. There are several ways to measure the diameter of the tank: measure the circumference and then figure out the diameter, or you can use two sticks and a tape measure. To use the circumference method, wrap a tape measure around the widest part of the tank and write that length down. You can then use the Circumference to Diameter formula (Diameter = Circumference divided by Pi) or you can search your favorite search engine for a Circumference to Diameter calculator. To use the stick and tape method, attach two rulers to opposite sides of the widest point of the tank and then measure the distance between them. You’re essentially making goal posts and using the tape measure to create a crossbar, which should give you an accurate diameter. Take out the cartridge to measure the diameter and length of the plastic end cap (end cap to end cap, not including the spout/tap found). For some, measure the length of the curved trellis to determine their size. Grates come in 5 different sizes in square feet; their respective lengths are 12, 18, 24, 30, and 36 inches. For older models like the Jacuzzi Earthworks and Avalanche, which use non-curved grilles, you must measure all grilles, as the different model sizes use a combination of two or three grille sizes per model.

A common question is, “What is the best filtration system for a hot tub?” The simplest answer is, it depends on what’s important to you, because at the end of the day, all spas filter water, some just do a better job than others.

I must first clarify that a filtration system is not the same as a filter, although the combination of the two can play a role in the end result. I explain both in this article.

There are typically three types of filtration systems found in a hot tub; Standard, circulating pump and no bypass with the circulating pump. You will find one of two types of filters on these systems, either polyester “paper” or ceramic.

What is the difference? Let’s take a look…

Introduction to Hot Tub Filters

Your hot tub filter is critical to the health of your hot tub. Nothing is more important. A filter’s job is to channel dirty and contaminated water from the spa into its system. Once the water enters, it is cleaned and then injected back into the spa for further use. This is important because you need to make sure the water you swim in is clean and free of debris or other potentially harmful objects.

When looking for hot tub filters, there are 3 different types of filters; Cartridge filters, diatom filters (D.E.) and sand filters. In the next three sections, we will detail how each of them works. This should provide some clarity as to which filter is the “best” for your needs.

Types of Hot Tub Filters

Hot tub filters come in 3 main styles:

sand filter

Sand filters are inexpensive filters with low maintenance requirements. These filter the least effectively. Sand filters are very useful for larger hot tubs because they don’t clog often. However, this type of filter can slowly erode and become less effective as pressure builds up in the filter over time. A sand filter usually lasts 5-7 years.

cartridge filter

Cartridge filters are a medium-priced filter. They are more efficient and clean better than sand filters. They are just as easy to maintain as a sand filter, but more effective in practice. A cartridge filter typically only lasts 3-5 years before it needs to be replaced.

EN filters

A DE or kieselguhr filter is the best, but also the most expensive filter type with the greatest maintenance. Like a sand filter, The D.E. Filter must be backwashed. A DE Fresh DE powder must always be added to the filter. Hardest working and best for general water purity (filters the smallest particles). A DE The filter does not need to be replaced very often, but the internal grille needs to be replaced every 2-3 years. These filters pose some health risks as the powder can cause eye irritation or lung damage if exposed.

Each of these offers different pros and cons that you need to know before you can make an informed decision. Below are the distinguishing features that match each type of filter:

Pros and cons of different hot tub filters

Spa Sand Filter

As the cheapest hot tub filter that consumers can buy, sand filters get the job done. In fact, given their reasonable price, they perform exceptionally well. These costs are also paired with a low maintenance effort on the part of the user. Gravity does much of the work for you, pulling the water out of the skimmer through the sand and filtering the water in a streamlined manner. This process runs almost entirely by itself. These filters typically last 5-7 years depending on how much work is required.

Sand filters need to master your water chemistry game. Being the least efficient of filters, sand filters can only capture and clean larger particles (20 microns or larger). This means that balancing your hot tub’s chemicals is key to killing off the smaller particles that may be lurking in your water. Your sand filter can handle the big dirt, but you’ll need to do extra work to match the purity levels of the other two filter types.

Cartridge filter for spas

Cartridge filters are an improvement over sand filters in both cost and efficiency. They represent a middle ground for consumers. This filter is neither too expensive nor too weak in terms of filter performance. Cartridge filters require more maintenance than a sand filter. Cartridge filters are based on a plastic cylinder surrounded by a polyester filter. Water enters through one end of the cylinder and particles as small as 10 microns (half the capacity of a sand filter) are caught and stored in the tank. The freshly purified water is then spewed through the “out” end of the cylinder and filtered back into the spa. Filters typically last 3-5 years depending on how much work is required.

These cartridge spa filters require constant cleaning. That means you need to be able to physically remove and rinse them off for them to be most effective. In addition, these filters must be occasionally sprayed with filter cleaner. This chemical mix is ​​necessary to keep your filter clean and running smoothly.

Jacuzzi D.E. filter

Diatom filters are often considered the “top dog” in the filter industry and are the most expensive of the three options. They also purify the water the deepest. This is reflected in the fact that D.E. Filters can remove particles as small as 5 microns (2x smaller than cartridge filters, 4x smaller than sand filters). You can rest assured that your water is clean and safe for all who use it. EN Filters are so effective because they use an internal grid covered with white powder made from diatoms (remains of tiny aquatic organisms) that help purify and filter the water.

This powder is used as a kind of “pest repellent” in your water and when used with the filter it can remove almost all waste from the water giving you peace of mind. EN Filters do not need to be completely replaced very often either, but the mesh inside the filter does need to be replaced every 2-3 years. For more information on maintaining a DE filter, watch the video here.

Disadvantage of D.E. filter

EN Filters have some notable problems. In addition to the high price mentioned above, constant maintenance of the filter is required. Additionally, the use of these filters at your site may be restricted due to regulations based on the environmental and waste risks associated with this filter. The diatom powder can be dangerous, and that means it’s not just possible environmental damage associated with this filter. The powder can be dangerous if directly exposed to humans for an extended period of time, but is not considered dangerous for swimmers. This means you need to be careful when handling the powder and take precautions like wearing chemical protective masks and gloves to avoid possible accidents.

Basics of the hot tub filter

Filters are a hot tub’s best friend; Your hot tub would be nothing without them. Therefore, having reliable and clean filters is essential for your hot tub to function properly. Here at HotSpring Spas & Pool Tables 2 we carry two different types of filters: paper and ceramic.

Paper is the most commonly used. They have hundreds of thin folds of paper that make up the body of the filter. In comparison, Tri-X ceramic filters have thicker, harder ceramic pleats that give them a different look compared to the paper filter.

Paper filters last 1 to 3 years depending on your source water, how often the spa is used and how often and how well the filters are cleaned. The same goes for the Tri-X ceramic filters; However, the ceramic filters last longer, around 3 to 5 years.

We recommend cleaning your filters with a degreaser every 30 days. A degreaser is needed to break down oils, skin cell buildup, and other impurities. After soaking your filters in a cleaner/degreaser for 12-24 hours, be sure to rinse your filters thoroughly. This is an essential step because if you have even the slightest trace of the degreaser and soap on your filter when you put it back in the hot tub, you could accidentally throw a foam party.

You can put Tri-X filters in the dishwasher without heat and without soap; Rinse only. However, we recommend soaking your Tri-X filter(s) in your cleaner/degreaser, removing them and popping them in the dishwasher for a thorough rinse. DO NOT PUT PAPER FILTERS IN YOUR DISHWASHER.

Ever wondered how you know when your filter is “dead” and when it’s time to get a new one?

Here are a few tricks:

If your paper filter sinks to the bottom of your hot tub when placed outside of the filter compartment and into the main pool, then you know it’s time to buy a new one.

When your Tri-X filter starts to change shape and turn into an hourglass, it’s time to replace it.

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.

You may see that the outside of the filter looks clean (if it survives the trip), but the spaces between each pleat will still be filled with dirt and grime.

Washing machines are notorious for rolling and tumbling clothes. This is fantastic for fabric because it deaerates and cleans every fiber. But you could even damage your washing machine if it bangs around in it too hard!

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.

Do you want to clean the wrinkles EASY?

While you can just flush the filter with your garden hose, I’ve found something that saves a lot of time cleaning out the pleats.

But it also makes it super easy to remove hair, leaves, and other debris that gets caught in your hot tub filter.

This product is called Filter Flosser

and it is the highest rated product of its kind on Amazon.

It simply screws onto the end of your hose, is curved like your filter, and has individual nozzles to get between the pleats.

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?

No problem! In a recent article, I cover everything you need to know about changing the water in your hot tub. I always cover the 1 tip for draining your hot tub in under 15 minutes!

While hot tubs are designed for relaxation, they require a little maintenance to ensure the water is clean and safe for users. One of the most important components of the system that requires regular maintenance are hot tub filters. However, cleaning hot tub filters is fairly easy, and the method depends on the type of filter you are using.

Common filter types for hot tubs

There are types of filters for hot tubs, but these four are the most commonly used in modern spas today.

Cartridge Filters: Cartridge filters are by far the most popular choice among spa owners and are typically made of paper, cloth, or plastic. These are made from pleated material housed in a plastic cartridge that simply slides into the filter housing compartment inside the spa.

Ceramic Filters: Similar to cartridge filters, these are made of a durable ceramic that generally outlasts all other types of filters. With regular maintenance, ceramic filters can last for several years before needing to be replaced.

Sand Filters: Sand filters are typically spherical containers filled with sand that removes unwanted substances. They usually sit outside of the hot tub and need frequent cleaning.

Diatomaceous earth filters: Eco-friendly diatomaceous earth filters use fossil diatoms instead of activated carbon, but work the same way as cartridge filters.

Regardless of the type of filter you use, regular care, cleaning and replacement of the hot tub filter.

How to clean a hot tub filter

The best way to ensure good water quality and increase the longevity of your hot tub is to clean the filters regularly. Regardless of the method you undertake, it is imperative to only use a hot tub filter cleaner that is recommended for your spa model. If you’re wondering how to clean hot tub filters, don’t worry, we’ve got you covered. Here are three recommended cleaning methods for hot tub cartridge filters.

Weekly Quick Flush – Once a week, remove the spa filter and rinse thoroughly with fresh water. Take the time to spread out the wrinkles and remove any debris or residue. Rinse the filter again and allow it to air dry before replacing it in the tub. Monthly Chemical Flush—Once a month, remove the filter and spray liberally with appropriate spa filter cleaner, which usually comes in a spray bottle. Leave the solution on for 15 minutes or as directed on the cleaner. Rinse thoroughly and place back into the spa unit. Chemical Soak – It is recommended that an overnight chemical soak be performed on the filters every three or four months and this is an ideal task when changing the spa water. Completely submerge the filter in a spa filter cleaning solution diluted according to directions and leave overnight. Rinse thoroughly, allow to dry and replace the filter.

When to change hot tub filters

Most manufacturers recommend changing hot tub filters once a year, with the exception of ceramic cartridges, which can last several years. If the cartridge is damaged in any way, e.g. B. by bent or torn media or brittle end caps, it is important to replace the unit immediately. Operating the spa with dirty or worn filters is not only unhealthy, it can also cause damage to the spa itself. In fact, operating the device with dirty filters can even void the warranty.

A quick summary of hot tub care for beginners

There are many types of hot tub filters to choose from, but all require regular cleaning and maintenance.

The spa filters should be flushed weekly and more thorough cleanings should be done monthly.

Never use household products such as bleach or dish soap in the spa or to clean the filters.

Annual replacement is usually recommended, depending on the type of filter used.

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.

Hot tub maintenance tips to help you avoid costly hot tub repairs and cloudy hot tub water

Hot tubs are a great way to relax and enjoy your own private oasis in your backyard. But even in this state of serenity, there are still things that can go wrong if you don’t take proper care of your hot tub.

So, to avoid costly hot tub repairs, do regular hot tub maintenance and avoid mistakes by following these hot tub don’ts.

Don’t forget to test the water (but don’t use pool chemicals)

You should test the water in your hot tub weekly, even if you do not use your hot tub regularly, and especially before entering it. Regular testing prevents chemical overdose and bacterial build-up. And balanced water chemistry will help keep your hot tub in good condition and safe to use.

Also, you should only ever use spa chemicals in your hot tub—never pool chemicals. Spa chemicals are designed to work in hot water and with hot tub surfaces. Spa chemicals also have precise dosing instructions based on the small size of hot tubs.

Don’t keep your hot tub full and running unless you’re maintaining the water

Without testing and treating the water weekly, your hot tub will cease to be a relaxing retreat. Instead, it becomes a stinky, bacteria-filled, swamp-like mess you never want to set foot in.

And it will take a lot of time and labor to thoroughly clean it and restore it to a safe, shiny condition.

Don’t ignore basic maintenance

Spending a little time on basic hot tub maintenance will save you a great deal of time and money in the future. Basic spa maintenance includes:

testing and treatment of the water;

testing and treatment of the water; rinsing the filters;

rinsing the filters; cleaning the cover; and,

cleaning the cover; and, wiping the waterline and refilling the drain.

You should also maintain a maintenance schedule, even if you don’t use your hot tub regularly.

Do not turn off the power or leave your hot tub full of water

To maintain a consistent hot tub temperature and avoid costly energy bills, keep your hot tub on at all times. The hot tub temperature will drop when it is turned off and it will cost you more to return to the ideal temperature.

In addition, stagnant spa water is a hospitable environment for bacterial growth. To keep your spa water circulating, filtered and sanitized, keep your spa running.

If you’re going out of town, keep your hot tub covered and have the pump timer set to circulate your hot tub water at high speed for a few hours each day and low speed all the time.

Although you don’t have to run the pump 24/7 in an indoor hot tub, your hot tub water does need to be circulated daily.

Running your hot tub in the winter will also prevent frost damage to the equipment.

Don’t let your cover become too heavy

Hot tub covers protect hot tubs, so be sure to protect your cover too. Clear your cover of snow and ice in winter to prevent damage from excess weight. If your hot tub cover becomes too heavy to lift due to a lot of snow accumulating on it, it will likely sink, tear and damage the lift.

Don’t leave an unattended hot tub uncovered either. Open hot tubs are a safety hazard for young children and animals.

An uncovered hot tub also gets dirty, loses water and chemicals through evaporation, and causes your equipment — especially your spa heater — to work harder, using electricity and costing you more on energy bills.

Do not overfill the hot tub

Overfilling a hot tub can happen when you become distracted and forget you ran the hose. While an overfilled hot tub may not cause component damage, some models may. So better safe than sorry.

Consider using a plastic timer that screws onto a hose and shuts off the flow of water after a set amount of time so you can reduce the risk of your hot tub overfilling.

As well as being careful to overfill your hot tub, be careful never to underfill it or you risk overloading the pump and sucking air into it.

Don’t run it without the filter

Running the pump too long without a filter in a hot tub can result in clogged pump impellers and a rapid drop in water quality. So if you need a new filter, replace it as soon as possible. In the meantime, only run the pump at low speed instead of turning it off.

Do not clean it with a high-pressure cleaner

Any type of pressure washer is too powerful for a hot tub, especially for cleaning cartridges. The high pressure pushes dirt, oil and debris deep into the filter mesh while damaging the fibers by separating and bunching them up.

Use a garden hose with a spray nozzle to gently clean your cartridge. Also, use a spa filter cleaner once or twice a year to remove dirt, debris and oil.

Do not remove the spa filters from the filter compartment and do not forget to clean them before they dry out

Be sure to clean the filters immediately when you remove them from the filter compartment. Otherwise you will have to buy new filters when they dry up.

Don’t forget to clean your filters

You should clean your filters every two to three months, even if you don’t use your hot tub regularly. And replace your filters every two years to ensure they keep your hot tub clean.

Don’t forget to change your silver ion cartridge

Change your silver ion cartridge every four months to keep it working efficiently and help keep the water clean.

Do not use the hot tub as a bathtub for bathing

If you’re dirty or sweaty, you’d better shower before jumping in your hot tub. Dirt, sweat and contaminants take a toll on your hot tub water, especially the filter, sanitizer and pH levels. As a result, your water becomes unbalanced and less hygienic.

You should also never add a bubble bath to your hot tub water unless you want all of the water to foam and drain out of your hot tub.

Don’t forget to check your ozonator regularly to find out if it’s working

Ozonators help disinfect the water. But if they don’t produce enough ozone for sanitation, then they’re useless. So make sure it’s working properly and producing enough ozone to get the job done.

Do not enter the hot tub if the water is green, has a musty smell, or is overflowing with foam

If your hot tub is green, stinks, or foaming, it is unsafe to use. Before using your hot tub again, drain and refill the water and follow the hot tub startup process for adding spa cleaners.

Do not cover your spa with clear plastic or enclose it in a plastic greenhouse

Clear plastic and plastic greenhouses amplify the sun’s rays and trap heat. As a result, the insulation in your hot tub cover could melt.

There are many benefits to using spas and hot tubs. So don’t spoil your fun by making these mistakes. Instead, take care of your hot tub so it can take care of you!

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.

A common question is, “What is the best filtration system for a hot tub?” The simplest answer is, it depends on what’s important to you, because at the end of the day, all spas filter water, some just do a better job than others.

I must first clarify that a filtration system is not the same as a filter, although the combination of the two can play a role in the end result. I explain both in this article.

There are typically three types of filtration systems found in a hot tub; Standard, circulating pump and no bypass with the circulating pump. You will find one of two types of filters on these systems, either polyester “paper” or ceramic.

What is the difference? Let’s take a look…

The size of your filter model should be marked by the manufacturer or the installer must do so during installation, but this is not always the case. To determine the size of your filter, you can measure specific parts of the filter to determine its size. Measure the diameter of the tank. There are several ways to measure the diameter of the tank: measure the circumference and then figure out the diameter, or you can use two sticks and a tape measure. To use the circumference method, wrap a tape measure around the widest part of the tank and write that length down. You can then use the Circumference to Diameter formula (Diameter = Circumference divided by Pi) or you can search your favorite search engine for a Circumference to Diameter calculator. To use the stick and tape method, attach two rulers to opposite sides of the widest point of the tank and then measure the distance between them. You’re essentially making goal posts and using the tape measure to create a crossbar, which should give you an accurate diameter. Take out the cartridge to measure the diameter and length of the plastic end cap (end cap to end cap, not including the spout/tap found). For some, measure the length of the curved trellis to determine their size. Grates come in 5 different sizes in square feet; their respective lengths are 12, 18, 24, 30, and 36 inches. For older models like the Jacuzzi Earthworks and Avalanche, which use non-curved grilles, you must measure all grilles, as the different model sizes use a combination of two or three grille sizes per model.
