What is a Jacuzzi Filter Cartridge?

If you’re new to hot tub ownership or just haven’t ever really looked into your spa, you might not be sure what a filter cartridge really is. Inside your hot tub (or nearby on the outside, depending on your model), you should be able to find your filter. This is the part of your hot tub through which you fill the spa, and water moves through the filter in order to remove bacteria, sediments, and debris before it gets to the tub portion of your spa.

the tub portion of your spa


Inside the filter housing unit, you can see the filter cartridge. Many filter cartridges have handles, but even if they don’t, this should be a large cylinder that is easy to recognize. This is the part of your filter that water passes through, and it is this cartridge that catches all of the unwanted materials in your water before it gets to you. It’s very important to keep your filter cartridge clean and replaced as often as necessary to make your water clean and safe for use.

Why Replace the Filter Cartridge?

Now that you know how to recognize your filter cartridge, you might be wondering why you need to replace it. Shouldn’t it be okay to just leave it alone and maybe clean it every once in a while? This might be true for some of your filter cartridge’s life, but overall, it’s very important to keep up with a regular replacement schedule. Check out this list to understand why it’s important to replace your filter cartridge.

  • Over time, filter cartridges may get too grimy or built up with debris. Even if you clean them often, eventually, it will be too difficult to remove all the build-up from your filter cartridge media. When this happens, your cartridge will be unable to be cleaned further, and it will be time to replace it with a fresh, new one.
  • Over time, filter cartridges may become damaged. The more you remove, rinse, soak, and replace your filter cartridge, the more chances it has to become torn, damaged, or weakened. When this happens, your filter cartridge will not be as effective anymore, and you’ll find that the whole filter won’t work as well.
  • Too much debris on your filter cartridge can damage your hot tub. If debris builds up too much in your filter, it might break loose and float into your pipes. From there, it can enter your jets or even your pump. If this happens, the repair bill could be significant. A blockage in your water pump is enough to completely break your whole hot tub system, and it will have to be fixed before you can continue to use your spa.
  • You might start seeing dirt in your hot tub water after a while. Even if your hot tub doesn’t get damaged, grime and dirt that builds up on your filter cartridge media may float into the bath portion of your spa instead. You’ll start to notice more of a slimy feeling in your water, and you might even see pieces of dirt and other objects floating in your spa. This definitely means it’s time to replace your filter.

How Often Should I Replace My Filter Cartridge?

Depending on the type of hot tub you have, you might need to replace your filter cartridge more or less often than you would with other types. Keeping up with a regular schedule of cleaning and replacing your filter is an important part of being a hot tub owner. Keep these tips in mind to be sure you’re always replacing your filter cartridge when the time comes.

  • For most filters, you’ll need to replace the cartridge every year. This is a good rule of thumb without any extenuating circumstances present.
  • If you have very hard or alkaline water, you’ll need to replace your filter cartridge every six months.
  • If you don’t use your hot tub all year long, or if you don’t soak in it very often, you might be able to get away with only replacing the filter cartridge every year and a half to two years. However, you should still remove and clean it as often as usual, which may weaken it even without regular use.
  • If you have a microfilter or secondary filter, it will need to be replaced more frequently than the regular filter will.

How to Install the Filter Cartridge

It’s very easy to remove your existing filter cartridge and replace it with a new one. Although every filter cartridge should come with directions on how to install it, and every hot tub should also include this information in its instruction manual, keep these tips in mind if you need a little more information to help you get started.

  • Turn off the power to your hot tub and drain all the water. You can leave the water in the foot bath if you like.
  • Locate the filter housing unit in your hot tub.
  • Open your filter housing unit and look for your filter cartridge.
  • Most Jacuzzi brand filter cartridges have a handle. If yours has a handle, grab it and twist it to the left to remove the filter cartridge.
  • If yours doesn’t have a handle, you may be able to pull it straight out.
  • Otherwise, there may be a couple of screws you will need to remove before you can get to the cartridge. You can remove these by hand with only a normal Phillips or flat head screwdriver.
  • When the old cartridge is removed, simply put the new one in by reversing the process. Slide it back into place and twist it to the right to install it.
  • If you had to remove any screws, put them back in by hand using a screwdriver.
  • Refill your hot tub through the filter and let it run at least one cycle before using it.
