How often should I clean my pool filter?

Pool filters should be cleaned regularly to keep your water clear and your equipment running efficiently, but the exact timing depends on the type of filter and how often your pool is used.

In general:

• Cartridge filters should be cleaned every few weeks during peak swimming season.

• Sand filters are typically cleaned by backwashing when pressure rises above normal operating levels.

• DE filters require periodic backwashing and occasional full cleanings.

Heavy use, storms, nearby trees, or algae issues may require more frequent cleaning. A dirty filter can reduce circulation, strain your pump, and lead to cloudy water or equipment problems if left unattended.
