c filters for pool

Search results list cartridge filtration areas including 45 sq ft, 120 sq ft, 150 sq ft, and 200 sq ft.

The listings recommend rinsing cartridges every 4–6 weeks during swim season and typically replacing them about every 1–2 years (some specify at least once a year). They also advise replacing a cartridge sooner if the filter pressure rises roughly 8–10 PSI above its normal clean reading.

The cartridge listings describe trapping visible debris such as leaves, bugs, hair, sediment, sand, silt, rust and other turbidity. By comparison, the D.E. filter is noted to capture much finer particles—about 2–5 microns.

Most replacement cartridges use pleated polyester fabric media (product details list "Material: Fabric" and "pleated polyester media"). The larger D.E. filter in the results is described as having a plastic housing.

Listings describe quick cartridge changes—typically about 5 minutes for a simple swap, with a full servicing or replacement taking up to about 15 minutes.

The results show single-unit and multi-pack options, including 1-pack, 2-pack, and 4-pack configurations.

The cartridge filters use pleated polyester fabric media that you rinse and periodically replace (commonly every 1–2 years). The D.E. unit uses diatomaceous earth as the filtering medium, captures much finer particles (about 2–5 microns), and is described with an extended-cycle, self-purging design that reduces the need for backwashing.
