How to Clean a Hot Tub Filter

Cleaning your hot tub filters & replacing them periodically is important to keep your hot tub working properly. Dirty filters can cause restricted flow through the pumps (the jets won’t be as strong) and even cause your hot tub to shut down. (Here’s a post on how to test if your broken hot tub is caused by dirty filter: The Hot Tub Filter test)

Different hot tub brands use different types of filters so be sure to consult your owner’s manual for your specific brand, but here are some general rules to follow:

Cleaning a Standard Hot Tub Filter

The most common hot tub filter is made from a light polyester fabric. The pleats run vertical between a plastic top & bottom. With proper care and cleaning, your filter(s) should last anywhere from 1-2 years.
