PSR100 Pleatco Advanced 100 sq ft Spa Filter Cartridge — Sta-Rite Posi-Flo

The Pleatco Advanced PSR100 is a 100 sq ft replacement filter cartridge engineered for the Sta-Rite Posi-Flo filter system. Built with Pleatco's Point Bonded Pool Filtration Fabric, it delivers consistent pore structure throughout the cartridge's life — resisting channeling and maintaining steady flow cycle after cycle. The open-centre Free Flow Core keeps operating pressure down by maximizing the surface area available for filtration.
