Hot Tub Filter Cartridges

Hot Tub Replacement Filter Cartridges

Hot tub filter cartridges work hard to capture the dirt, debris, oil and general grime that’s present in your water. The pleated paper or fabric of the cartridge traps tiny particles when your pump passes water through the filter system.

While hot tub cartridge filters are relatively sturdy, they won’t last forever. Because they do so much heavy lifting to keep your water contaminant-free, you will need to replace your cartridge around once a year. These filters are very affordable, so it’s worth swapping them out when you notice your old filter begins to deteriorate. 

If you don’t replace your hot tub cartridge filter when necessary, it won’t be as effective as removing pollutants, leaving you with unclean, unpleasant water even if you’re using all the right hot tub chemicals. 

How to Clean a Hot Tub Filter Cartridge 

To ensure your filter cartridges stay in top form for as long as possible, it’s a good idea to clean them regularly. A simple rinse with water every few days or between each use will quickly get rid of any build-up in the filter. 

In periods of heavy use, you should also use a hot tub filter cleaner once a week to ensure your filter is completely free of dirt and can capture newly introduced pollutants more effectively. Leave your filter to soak in a filter cleaner solution for several hours before thoroughly rinsing it with water and returning it to your hot tub. 

You can also use filter cartridge cleaning nozzles that attach to your hose to make flushing out every part of the filter much easier.
