Pleatco replacement swimming pool/spa pool filter cartridge # PGS25P4 replaces Unicel 4CH-24, Filbur FC-0131, and After Hours Spas, Threaded 25 sq.ft. w/handle swimming pool/spa filter cartridges. Pleatco premium filter cartridges employ Free Flow Cores, specifically engineered to allow for the even flow of water through the entire cartridge which increases filtration (best efficiency), uses greater media surface to inhibit the growth of bacteria mold & algae (best water quality), and makes it easier for the pump to pull more water through the cartridge (less wear & tear and expense).
