It is time to clean the filters when you notice a decrease in the pressure from your jets, or when the pressure in your filter tank increases by 8 psi from when the filter was newly installed.

In order to clean the filter;
  • First remove it from its canister and use a garden hose to dislodge any debris between the pleats.

  • Soak the filter in commercially prepared filter cleaner, or spray with the same to remove organic material and oils. To remove stains soak overnight in a solution of one quart bleach and 5 gallons water.

  • Thoroughly rinse the cartridge with fresh water and reinstall it into the canister. Be sure to follow manufacturer's directions for installing the filter.

  • DO NOT use a high-pressure car wash wand, a stiff brush or acid wash to clean the filter cartridges as these methods can damage the filter media.
