How To Clean A Pool Filter Cartridge

When should a cartridge element be cleaned?

For swimming pools, clean the cartridge when filter canister pressure reaches 10-12 PSI above the initial system or new cartridge starting pressure. Cartridges should be rinsed at least once every 2 weeks. Cartridges should be chemically cleaned in Filter Cleaner at the end of every season before they are put away for winter or anytime you have had to treat the pool for an algae bloom.

What is the procedure to clean my cartridge?

Weekly

  1. Remove the cartridge from the filter housing following the manufacturer's instructions.
  2. Use a garden hose with a straight flow nozzle to wash down the filter element.  Work from the top down, holding the nozzle at a 45o angle, and wash all the pleats with emphasis between pleats. Never use a pressure washer as this will damage the filter.
  3. Rinse until all dirt and debris is gone.
  4. Return to filter housing while still wet.

 

Chemically Cleaning Filter

  1. Remove the cartridge from the filter housing following the manufacturer’s instructions.
  2. Use a garden hose with a straight flow nozzle to wash down the filter element.
    1. Work from the top down, holding the nozzle at a 45o angle, and wash between the pleats.
    2. Never use a pressure washer as this will damage the filter.
  3. Soak the element for a minimum of six hours in a solution of Filter Cleaner and pool water.
    1. The solution will depend on height of filter – can be determined using the back of the bottle.
    2. Ensure that the entire filter is submersed in the solution.
  4. Rinse the cartridge again to remove oils and cleaning solution.
  5. Let the cartridge air dry completely before installing it back into the filter housing or storing for winter.

When chemically cleaning, the pump will need to remain off for the duration of the soaking process.
