What Is a Cartridge Filter?

A cartridge filter is a cylindrical component that contains an accordion-folded polyester fabric that traps dirt and debris as pool water is pushed through the filter. Unlike sand filters or diatomaceous earth filters, a cartridge filter needs to be cleaned by hand, since it can become clogged by dirt, leaves, and more.


How Often Should You Clean the Cartridge Filter?

It’s important to have a regular pool cleaning routine, and you can hose your cartridge filter off once a month or after any major storm or heavy pool use. The cartridge filter should be cleaned with a filter cleaner at least twice a year, as well as any time you notice the filter’s pressure gauge is 8 to 10 psi over the normal range.


Supplies You’ll Need

You will need a few things to clean your cartridge filter, including:

  • Garden hose
  • Spray nozzle
  • Filter cleaner
  • Clean five-gallon bucket or small trash can
  • Lubricant (non-petroleum based)
  • Replacement filter cartridges (if necessary)
  • Replacement filter tank O-ring (if necessary)
  • Pool owners manual
  • Cartridge product manual

With these supplies, you can successfully clean your filter and keep it working as it should for a long time!


Cleaning the Filters

It’s fairly simple to clean your cartridge filter, but it’s important to be precise so nothing gets damaged. Make sure your pool pump is turned off at the breaker, and let any air or water out of the filter. Check each filter for any damage, and replace any filters that are cracked or torn. If it’s particularly dirty, you can soak the filter overnight in a solution of one part filter cleaner and three parts water, rinsing them out the next morning. Once everything is clean, replace the filter and turn the system back on.
