How Often Should You Change Your Pool Filter?

Whether your in-ground pool uses a sand filtration system, diatomaceous earth (D.E.), or a cartridge system, at some point, you’re going to have to swap out the filter. The trick is to know whether your filter needs a good cleaning or if it’s time to replace it altogether. It’s always a good idea to call a pool pro to schedule an inspection when in doubt.

Don’t Let A Bad Filter Ruin Your Summer Of Fun

The purpose of a pool filtration system is simple: it helps keep the pool clean from visible debris and dirt. This enables the chemicals to do their job of destroying bacteria and keeping algae and other contaminants at bay.

A properly functioning system is the first step to maintaining a safe and sparkling clean fun zone during the swimming season.

Maintaining A Traditional Sand Filter

Sand systems are the oldest and a widespread type of pool filter. They are straightforward and inexpensive to operate, and the sand only needs to be replaced every 5-7 years, so long as the filter is regularly backwashed.

Backwashing is a process that reverses the flow of water through the media (sand) to remove and flush out trapped dirt and debris. Check your manual or consult a pool cleaning professional to determine how frequently you need to perform this necessary task.

When To Replace Your Sand Or Sand Filter

  • The Sand Is Gunky Or Oily
  • The Filter Tank Is Leaking
  • Your Filter Leaks Sand Into The Pool
  • The Multiport Handle Is Broken
  • High-Pressure Readings

D.E. Filter Maintenance

D.E. filters resemble sand systems, except for the medium used. Diatomaceous earth is a natural type of sand composed of fossilized algae called diatoms. D.E. provides a superior level of filtration but is also more expensive and a bit more finicky in terms of required maintenance.

Like sand filters, those using D.E. should be backwashed and cleaned regularly.

Signs Your D.E. Filtration System Needs Repair Or Replacing

  • Consistent High-Pressure Readings
  • D.E. Leaks Into The Pool
  • Leaking Valves
  • Leaking Drain Plugs
  • Leaking Air Bleeder
  • O-Ring Won’t Stay Sealed

What About Cartridges?

Small pools and hot tubs often employ a filter cartridge system. These are less expensive than sand and D.E. systems but also less effective. Cartridges require frequent cleaning — at least once a week — to keep them from getting clogged with dirt and debris.

When To Replace Filter Cartridges

  • High-Pressure Readings
  • Torn Or Frayed Fabric
  • Broken or Cracked End Caps
  • Collapsing Cartridge Core
  • Filthy Appearance Won’t Wash Clean
