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?

Cover Life ExtenderThe 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.

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

Do The Bath Tub Filters Need Cleaning – Checklist:
  • 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 is usually one 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.

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? If any of these apply, you may have a clogged filter.

Take out the filter cartridge and view it again. Does it look dirty? Is it yellow, green or grey? If so, it’s time to clean it. You need to do a more thorough clean if you notice dirt in your filter.

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.
