Give your Pentair Sta-Rite System 3 S8M500 filter a fresh start with the factory-original 170148 cartridge replacement kit. This dual-element package pairs an inner cartridge with 209 square feet of media area alongside an outer cartridge providing 291 square feet, totaling 500 square feet of particle-trapping surface. Both elements are constructed from reinforced polyester pleated material capped with solid polyurethane end pieces, forming a reusable filtration solution that preserves outstanding water transparency and supports longer intervals between cleaning.

Key Benefits

• Durable Pleated Polyester Media: Reinforced polyester pleats bonded to sturdy polyurethane end caps create a cartridge built for repeated cleaning and reinstallation without loss of structural integrity.
