The Pleatco Advanced PSR137 is a 137 sq ft replacement filter cartridge engineered for precision fit in Sta-Rite Posi-Flo II cartridge pool filters. Built with Pleatco Point Bonded Pool Filtration Fabric, it delivers consistent pore structure throughout the cartridge's service life — resisting channeling and maintaining filtration performance from the first cycle to the last. At 31-1/4" long and 8-11/16" in diameter, the PSR137 meets the exact dimensional specifications of the original equipment cartridge.
