What is a Jacuzzi Filter Cartridge?

Jacuzzi filter cartridges are specialist filters that only work in bath tubs. It removes any bacteria, dirt, debris, contaminants and viruses before they enter into the bath water. This is especially necessary if your bath tub is out side where it can be affected by the elements.

It is more effective than simply washing your tub by hand because washing by hand means that you’re dealing with the dirt after it’s already reached your tub. While the filter will take care of it before it reaches your water.

Also remember that a lot of microorganisms are not visible to the naked eye. And this can become a serious issue if you’re sharing your hot tub with someone else.

It is very important to keep the filter cartridge clean and replace it as often as is necessary. Doing this will ensure that the filter will continue to keep your water clean and safe.

Why Replace My Jacuzzi Filter Cartridge?

No filter cartridge lasts forever. Sooner or later it will wear out and stop working effectively.

A worn out filter is as good as having no filter because it won’t do anything.

In fact, it might be worse than having no filter because if it’s full of dirt then some of that dirt might escape into your bath water.

Here’s why you need to replace Jacuzzi filter cartridges:
  • Over time, your Jacuzzi filter cartridge will accumulate too much dirt. This is because it is not always possible to remove all the dirt that has built up even if you clean, rinse and wash the filters frequently. The filter cartridges can no longer be cleaned at a certain point and it will be time to replace it with a new one.
  • There will be lots of things that enter your tub without a properly functioning filter. And these things entering your tub can cause damage to your pump, nozzles and the pipes. The repair bill for fixing this will be much more expensive than simply buying a new filter in the first place.
  • The filter will wear out overtime the more you remove, clean, soak, rinse and replace it. Filter damage is inevitable. Cracks, breaks and eventual looseness will cause your filter cartridge to be less effective.

How Often Should I Replace My Filter Cartridge?

It depends on the type of filter you have but 1-2 years is the average.

As previously discussed, you should check the manufacturer instructions to know exactly how long your filter will last for. There are some extremely high quality filters that can last for up to 5 years.

Also, remember that even though it might last for 1-2 years you will still need to clean and rinse it regularly. This is the only way to keep the filter working effectively long term.

Regularly cleaning and replacing your Jacuzzi filter is an important maintenance step that you need to conduct to keep your hot tub healthy.

How To Install A Filter Cartridge

The hot tub filter cartridge looks like a large white cylinder so it is easy to recognize.

You will find it inside its housing unit that is part of the tub.

If you’re struggling to find it then check your user manual or look through YouTube videos.

If neither of these help then try looking online for the user guide for your specific model.

Once you are able to locate where the filter is then follow the steps below:

  • Start by turning the power off at the service disconnect or breaker.
  • Take off the filter cover.
  • Open the bleeder valve and let the pressure release. This might take 10 seconds or so.
  • Once this has happened, tighten the bleeder valve back up. Don’t over tighten.
  • Then turn the lock ring and take that out.
  • Pull up on the handle section, take that out and put it to the side.
  • Now you can take out the filter.
  • Put your new filter in place of the old one.
  • Place the filter lid back on and press it down until it is air tight.
  • Take your locking ring and screw that back into place.
  • Turn the breaker back on.
  • Put the spa power back on.
  • Fill your spa through the filter and let it run for at least one cycle before using.
