Pentair Clean & Clear® Plus 420 Sq. Ft. Cartridge Filter

The Pentair Clean & Clear® Plus 420 Square Foot Cartridge Filter is a high-capacity, commercial-grade filtration system engineered to provide superior water clarity for large-scale residential swimming pools and heavy-use spa configurations. Utilizing a precision-engineered network of four heavy-duty cartridge elements, this unit boasts an expansive 420 square feet of effective filtration area that captures microscopic dirt and suspended particles down to 20 microns, significantly extending the operational cycles between cleanings. The single-piece tank body is crafted from injection-molded, fiberglass-reinforced polypropylene, offering exceptional structural strength and lifetime corrosion resistance against harsh weather and pool chemicals. By relying entirely on high-surface cartridge technology, the system eliminates the need for backwashing, preventing unnecessary water waste and chemical loss. It features balanced internal hydraulics that support a maximum design flow rate of up to 150 gallons per minute (GPM) via its 2-inch plumbing connections, allowing pool owners to pair it with modern variable-speed pumps for maximum energy efficiency. Routine servicing is simplified by a rugged steel tension control clamp ring with a heavy-duty barrel nut for quick tank access, alongside an integrated continuous High Flow™ internal air relief system and a convenient 1-inch bottom drain for rapid winterization. The dry weight of the Pentair Clean & Clear Plus 420 Cartridge Filter is approximately 74 pounds, standing as a highly durable, eco-friendly, and ultra-efficient filtration core for premium pool maintenance.
