Spa and Swimming Pool Filter Maintenance

It is vital that your filter cartridge is maintained correctly to maximise its life and usefulness.

The Importance of a  Well-Maintained Cartridge

The life of a filter cartridge depends on how you treat it.

Filter clogging is caused by soaps, chemicals, perspiration, body fats, oils and fine particles of dust or dirt.

Maximise the Life of Your Filter

  • There are specific things you can do to maximise the life of your filter:
  • Maintain the pool water chemistry in proper balance.
  • Clean the cartridge in accordance with its cleaning instructions.
  • Do not scrub the filter with a stiff brush.
  • Do not use a high-pressure hose.
  • Do not use flocculants.
  • Rotate two cartridges to prolong the life of the filters considerably.

Instructions For Cleaning Your Filter Cartridge

All cartridge filters should be cleaned at least every 1–2 months (more often with high usage). If you follow these cleaning procedures, you will ensure the maximum life of the cartridge:

  • Remove the cartridge from the filter housing or skimmer box.
  • Wash the filter using a garden hose or a cleaning tool, working from the top down.
  • Do not use a high-pressure hose or a brush.
  • Soak the cartridge for at least an hour (overnight is preferable) in a cartridge cleaning solution, which you can purchase from your local spa & pool shop.
  • Alternatively, use 1 cup of a household detergent in 5 litres of water to clean.
  • Rinse the cartridge once more with a hose or a pool filter brush to remove any remaining oils or cleaning solution.


Eventually your cartridge filter will block and will need to be replaced – usually within 1 to 2 years – depending on the amount of use.
