Pool Filter Replacement

A simple pool filter cleaning once a month will do, but the filters do need to be replaced periodically, although regular cleaning will reduce the frequency with which that is done.

If even after you clean the cartridge, the flow of water is not as much as it should be, then you definitely need to replace it.

The same holds if the pleats of the cartridge are flattened or damaged, the fabric is fraying or the end caps are cracked.
