Pool Filter Hacks

A clean filter is the heart of a clear pool. These pool filter hacks help water circulate better and stretch the life of your cartridges, so you replace them less often and use fewer chemicals.

Filter care schedule

Item Why it works
Weekly Empty skimmer and pump baskets
When pressure rises 8 to 10 psi Rinse or backwash
Monthly in season Deep clean cartridge
End of season Soak and store dry
Every 1 to 3 years Replace cartridge, depending on use

Cleaning hacks

  1. Note the clean starting pressure with a marker on the gauge.
  2. Rinse from the top down at an angle between pleats.
  3. Use a pleat-cleaning wand on your hose.
  4. Soak in a filter cleaner after heavy algae or sunscreen use.

Make cartridges last

  1. Own two cartridges and swap them while one dries fully.
  2. Fit skimmer socks to catch fine debris before it reaches the filter.
  3. Skim the surface daily so leaves never reach the filter.
  4. Avoid pressure washers, which damage the fabric.

Circulation boosts

  1. Angle return jets downward and in the same direction.
  2. Run the pump at the right time, usually during the day.
  3. Keep the water level at the middle of the skimmer opening.
  4. Brush dead spots behind ladders and steps.

Tip: Always switch off the pump before opening the filter housing and release the pressure valve first.
