How to Clean a Swimming Pool Filter Cartridges

Filter cartridges should be cleaned whenever the filter pressure increases by 8 PSI or more about normal operating pressure. It is also recommended that you should clean cartridges every 6 months.  If you are able to keep your filter cartridges clean, it will not only help keep your pool clean, but the cartridges will last longer.  For a simple how-to guide, follow our simple steps to cleaning your filter cartridges.

How to clean my filter cartridges?

  1. Purchase new Filter Cartridges at PoolZoom.
  2. When the filter cartridges become dirty, remove them from the pump-filter assembly following the manufacturer’s instructions.
  3. Use a garden hose and rinse any debris from the filter, wash down the filter element. Work from the top down and wash between each filter pleats.
  4. Rinse filter cartridge until all dirt and debris are gone.
  5. After initial clean let dry in the sun for up to 2 hours. After drying, brush, shake or use an air compressor to remove debris particles from the filter’s fabric.
  6. For all spa cartridges and elements used in swimming pools where perspiration, suntan lotions, and other oils are present, soak the cartridge for 1 day in a solution of 1 part commercial cleaner to 5 parts water, or one cup dishwasher detergent to 5 gallons of water.
  7. Remove the filters from the cleaning solution and rinse with clean water.
  8. If the filter has a coating of algae, calcium carbonate, iron, or other minerals, soak the cartridge in a solution of one part muriatic acid to twenty parts water until all bubbling stops. WARNING: Failure to remove all oils and cleaning solution before acid soaking will result in a permanent restriction of water flow and cause premature cartridge failure.
  9. Allow the filter to dry thoroughly in the sun. Any debris that might be leftover should be brushed off.
  10. Rinse the cartridge clean and reassemble housing.
