How Often Should a Pool Filter Be Cleaned?
A pool filter should be cleaned according to its type, debris load, and rise above the clean-pressure baseline—not by a single universal schedule.

What homeowners should know
Record pressure after a proper cleaning.
Watch for weaker return flow or longer clearing time.
Expect seasonal debris to change the interval.
Damaged media may require replacement, not cleaning.
Why the recommendation depends on the pool
Shut equipment down before service and use the filter manufacturer’s procedure. A damaged or pressurized vessel requires professional attention. The right decision depends on verified readings, equipment condition, recent weather, pool use, and the written service scope.
