How to Tell if Your Hot Tub Filter Needs Cleaning

You may be wondering if it is possible to simply clean the filter so that you reduce the need to thoroughly clean the tub after each use?

The short answer is yes.

You can and should clean the filter more often than the rest of the bath tub. Filtered water means a cleaner bath tub and less bath tub cleaning time.

However, do not forget to also periodically clean the entire bath so as to stop bacteria developing within the bath tub. This is because although the water will run through filters, it will do nothing if the bath tub is already filthy.Cover Life Extender

Why Keep Your Hot Tub Filter Clean?

The hot tub filter is supposed to keep your tub water clean but unfortunately it is not self-cleaning.

Remember that your tub cleaner will come into contact with bacteria, dirt, debris and other contaminants. All of this means that the filter itself will probably need to be cleaned from time to time.

Keeping your tub filter clean makes it run more efficiently and do its job better.

Why It’s Essential To Keep Bath Tub Filters Clean:
  • 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. Tub Pool Filter
  • 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.
  • 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.
  • A clean hot tub filter can protect you from injury. I know this sounds extreme but if your filter is clogged with sticks or other debris, there is always a risk that it may get into your water. It can then float when the nozzles are turned on. If they are sharp then expect cuts. This means that it can damage both you, the filter and the tub itself.

Here are 4 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 an easy, stress free hot tub filter cleaner.

Materials Needed:
  • 5 gallons of water.
  • 1 cup trisodium phosphate.
Process:

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 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 cheap substitute.

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

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.

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, 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.
Process:

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 solution.

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

5. After soaking, rinse the filter well with clean water.

6. Put the filter back in the hot tub.

3. Cleaning Hot Tub Filters With Vinegar

Using vinegar to clean your tub is a much gentler cleaning method than the previous 2 solutions. 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 cartridge.

Materials Needed:
  • Five gallons of water.
  • Three cups white vinegar.
Process:

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.

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

6. 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.

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

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

4. Let it soak for about 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.

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. However, keep the following tips and tricks in mind so you can make sure your tub stays in a good condition and lasts for many years.

  • Run water quality tests from time to time by using a water test kit. 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 or an ineffective filter.

  • Buy a second set of filters to switch to while cleaning. That way you will not have any idle time between tub cleaning. While one filter is drying, you can easily replace it with the other one. However, 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. This is because 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 bath tub.
More tricks…
  • 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.AquaCheck Test Kit
  • 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.
