How to Tell if Your Hot Tub Filter Needs Cleaning

If you do not thoroughly clean your tub, you may be wondering if it is possible to simply clean the filter and continue to use the tub without taking many complicated steps. The short answer is yes. You can and should clean the filter more often than the rest of the bath tub. However, do not forget to periodically clean the entire bath so it runs smoothly and the water remains safe and clean so you can use it at any time.

If you are not sure if your filter needs cleaning, have a look at this checklist to see if it’s time.

  • Is your water dirty? Do you notice that the water is taking on a strange color? Or do you see lots of debris floating on the surface of your water, then it’s probably time to clean the filter. This may also be a sign of a filter that needs to be modified. This is because visible signs of dirty water are usually some of the last things you notice if the filter does not work as it needs to.
  • Does your water feel strange on your skin? If your filter is not working properly or is clogged, your water may feel too hard or too soft. You may notice that your skin feels strange after leaving the bath. Soft water can feel too slippery, hard water can feel dirty or scaly. If you notice any of these, your filter could be the problem.  
  • Have you noticed any problems with your hot tub? Are there sounds that sound like air in your pipes? Do you hear strange noises from your pump or do you see smoke or other visible signs that the pump is working too hard to do its job? Are your jets working the way they should or are you having trouble moving the water? If any of these apply, you may have a clogged filter.
  • Does the filter look dirty? Take out the filter medium and view it again. Does it look dirty? Did it turn yellow, green or gray? If so, it’s time to clean it. You need to do a more thorough cleaning if you notice dirt in your filter. So simply rinsing is not enough. If you also notice an accumulation of calcium then you may need to buy a special solution to remove calcium from the filter.
  • Is it two weeks since your last cleaning? In this case, it may be time to clean the filter again. Check if it looks dirty. If it is not very dirty, you can do it by rinsing it with clean water from your garden hose every two weeks. This can help to improve the functionality.
  • A month or more since your last cleaning? If so, it’s time for a deep and thorough cleaning. Use the mixes later in this article and follow the instructions in the previous section. Each month you need to soak the filter medium and allow it to dry completely before returning it to the tub.
  • The last filter installed more than a year ago? If so, it’s probably time for a new filter. However, some filters can easily last two years, especially if you do not use your tub often. You can see if your filter needs to be completely replaced.

Why Keep Your Hot Tub Filter Clean?

You may feel that cleaning the filter in your hot tub is a somewhat arbitrary task. It seems that there is a lot of work that needs to be done only for something that keeps your water a little cleaner, right? However, you probably do not know how important it is to keep the tub filter clean for as long as possible. Some of the key concerns are listed below.

  • Regular cleaning of the bath tub filters can improve the functionality of all its parts. If the filter in your tub is clogged, the pipes and pump must work harder to keep the water clean. It is possible to overheat the pump in this situation, which can be a very expensive problem. Some contaminants that can get caught in a clogged filter can also get caught in the pipes, damaging the pipes and destroying the pump. Finally, a dirty filter can cause the jets to work harder to move the water. And they can also become clogged with debris and bacteria. This can damage the nozzles. If you are interested in extending the life of your tub and all its parts, the first step is to keep the filter clean.
  • Regularly cleaning your filter will ensure that the water in your tub is safe for you and your family. When the filter stops working, the water in the tub becomes increasingly  dirty. In some rare cases, it is even possible for dangerous bacteria to grow in the water, which can make your family sick. Even the least problematic bacteria can sometimes cause a problem, so it is in everyone’s best interests to keep the filter as clean as possible.
  • A clean hot tub filter can protect you from injury. If your filter is clogged with sticks or other debris, there is always a risk that it may get into the water and float when the nozzles are turned on. Some types of deposits can cut you, or they can damage the tub shell, which can also cause cuts and scratches.

How to Clean a Hot Tub

Before you start making your own homemade bath tub filter cleaner, it’s a good idea to get familiar with cleaning a hot tub from start to finish. That way, you will not get confused when the time comes to actually use the cleaner filter you created. And you’ll have a better idea of what the process generally means. You will know exactly how to use the solution and where it fits in the cleaning process.

  • Empty your hot tub. This is easy to do, and the process by which you can do it is usually described in your manual. However, you may also want to think about rinsing your bath pipes before performing this step. Since pipes connected to your tub collect bacteria and mold, it is often a good idea to clean them while cleaning the rest of the tub.
  • Drain the tub by turning off the power first. So you stay safe and you get extra security. If you do not turn off the power, you can damage the pump by operating it without water.
  • Follow the instructions in your manual to empty your tub. You may need a garden hose or other type of hose, and you may need to use built-in parts that come with your tub. Each bath tub is different and only your manual can give you a step-by-step guide to getting it right for your model. 
  • After draining the water, use a tub cleaner to scrub the outside surfaces of the tub. Depending on the type of bathtub you have, you may need to buy another type of cleaner. You can find certain cleaners for bath surfaces. But you can also use household items. Acrylic baths can be cleaned with a standard bath cleaner or with ¼ teaspoon of chlorine diluted in five gallons of warm water.
  • Rinse the inside of your bathtub thoroughly with the hose from your garden. Wipe it off with a towel. Do not leave any residue in the tub as these can cause damage and alter the balance of chemical treatments in the water.
  • Remove the filter and clean it. Most of the time, your filter can be removed by hand, but you may need to use a screwdriver. Use the hose in your garden to rinse the filter thoroughly. Put it in a large plastic bucket and immerse it in water. Add your filter cleaning solution to the water and soak for about two hours.
  • While the filter is soaking, clean the inside of the filter area with the bath cleaner. This prevents the formation of bacteria in the environment and leads to malfunction of the filter.
  • Rinse the filter after soaking with your garden hose. Allow to dry completely before returning to the tub. In most cases, you can put it back in the tub the same way you removed it.
  • Add water to your tub in the same way as when setting up. See your manual for more information.
  • Restore energy to your tub. That’s it, the cleaning process is complete!

You can control how much you use, and you can reserve all the left over resources for your next use. This is a great inexpensive way to keep your filter clean for a long time.

Here are a few different ways of making your very own homemade hot tub filter cleaner.

1. Cleaning Hot Tub Filters With TSP

Perhaps the most common recommendation for making your own filter cleaning solution at home is to use TSP. Follow these instructions to obtain a solution that will provide you with a easy, stress free cleaning at all times.

Materials Needed

  • 5 gallons of water
  • 1 cup trisodium phosphate 


1. Fill a plastic bucket with 5 gallons of water. If your filter is larger than your 5 gallon container then you may need to double the mixture in order for the filter to totally submerge.

2. Add the 1 cup of trisodium phosphate to the water and stir it well to mix. Make sure that you are using 100% real TSP and not a cheaper substitute.

3. Place the filter in the water and make sure it is completely covered.

4. Soak the filter for 1 to 2 hours.

5. Take the filter out of the water and rinse it completely with your garden hose.

6. Let the filter dry overnight before you put it back in the hot tub.

2. Clean Hot Tub Filter Dishwasher Detergent

Like TSP, dish washing powder or detergent is a common way to clean a dirty filter. The good news is that this is a much cheaper method than many others on the market, so it is very popular. It is also something that you’re very likely to already have at home.

Materials Needed

  • Five gallons of water
  • One cup of dishwashing detergent 


1. Fill a plastic bucket with 5 gallons of water. If your filter is larger than your 5 gallon container then you may need to double the mixture in order for the filter to totally submerge.

2. Add your cup of dishwashing soap to the water and combine it well by stirring.

3. Submerge your filter completely in the dishwashing detergent water.

4. Leave the filter alone and let it soak for 1 to 2 hours.

5. After soaking, rinse the filter well with a garden hose and clean water.

6. Do not put the filter back in the hot tub until it is completely dry.

3. Cleaning Hot Tub Filters With Vinegar

Using vinegar to clean your tub is a much gentler cleaning method than the previous 2 methods. This is a good option if your filter is not very dirty, but remember that you need to use something stronger if there is a lot of dirt in your filter media.

Materials Needed

  • Five gallons of water
  • Three cups white vinegar


1. Fill a plastic bucket with 5 gallons of water. If your filter is larger than your 5 gallon container then you may need to double the mixture in order for the filter to totally submerge.

3. Put the filter into the vinegar water and submerge it completely.

4. Let it stand for one to two hours to soak very well.

5. Remove it and rinse it with your garden hose.

6. Let it dry completely before you replace it in your hot tub.

4. Cleaning Hot Tub Filters With Bleach

Cleaning hot tub filters with bleach is popular. It’s old-fashioned. Bleach is a way to keep the water in the hot tub always clean. Remember, however, you should not use chlorine to clean your tub filter. This is because many filter cartridges can not withstand chlorine over a long period of time. Primarily because chlorine is a very strong chemical.

Materials Needed:

  • 1 garden hose
  • ¼ cup of bleach
  • 1 old towel
  • 1 large pickle tub container
  • 5 gallons of hot water 


1. Remove the filter cartridge from your hot tub and place it in the pickle container.

2. Use the garden hose to add 5 gallons of hot water to your pickle container.

3. Stir in the ¼ cup of bleach until mixed well.

4. Let it soak for 2 hours. Do not soak overnight.

5. Remove the filter and use your garden hose to rinse it completely of any remaining bleach residue.

6. Let the filter dry overnight or up to 24 hours.

7. Use the old towel to remove any lingering bleach residue from the filter.

8. Replace the filter cartridge in your hot tub.

9. Fill the hot tub through your filter and turn it back on.

Tips and Tricks for Cleaning Your Hot Tub Filter

It can be difficult to understand the best way to clean your hot tub filter. Keep these tips and tricks in mind so you always know what you are doing and that your tub is as clean as possible with every cleaning session. That way, you can make sure your tub stays in a good condition and lasts for many years.

  • Run water quality tests from time to time. Although it is not necessary to do this every month. It is a good idea to run a water quality check twice a year. This will make sure everything in your tub is working properly. If the water quality control shows signs of bacteria or other water problems, you may have a dirty filter. This means that you have to work to clean it more often. 
  • Buy a second set of filters to switch between during cleaning. That way you will not have any idle time between treatments in the tub. While one filter is drying, you can easily replace it with the other one. Be sure to keep track of how many times you have used each one so you can throw them away when the time comes.
  • Do not use filters from manufacturers outside your tub brand. They may not work well and may not work as well as official filters for your particular tub. Always use products approved by the company that makes your tub so as not to damage your bathtub.
  • Always remove visible dirt from your filter when you notice it. If you see leaves, sticks or other residue on your filter, remove it immediately. These can damage your filter and cause many problems when sucked through the pipes.
  • Check your filter every two weeks, but expect to clean it once a month. If your filter does not look very dirty during your two-week inspection. You may not need to do more than simply rinse it off with your garden hose. Sometimes, if you soak your filters too often, they can wear out faster. Therefore, it is worthwhile to pay attention to the dirt of your filter.
  • Discard the filter after two years. There are a handful of long term filters on the market. But in most cases it is a good idea to throw the filters out every two years. However, check them after one year. As they may need to be replaced at this time, depending on how many times you have used your tub.
