Excel Filters makes direct-fit replacement cartridges for Sta-Rite® Posi-Clear filters: the PXC line (PXC-75, PXC-95, PXC-125, PXC-150) and the PXCRP line (PXCRP 100, 150, 200). The two families use different cartridge geometries, so match your tank model or the part number on your current cartridge.
