Pentair 520 SqFt Clean and Clear® Plus Cartridge Filter

Pentair Clean & Clear® Plus 520 Sq. Ft. Cartridge Filter

The Pentair Clean & Clear® Plus 520 Square Foot Cartridge Filter is the flagship, maximum-capacity filtration system designed to provide ultra-pure water clarity for massive residential swimming pools and heavy-duty commercial spa configurations. Utilizing a precision-engineered bank of four extra-large cartridge elements, this unit delivers an expansive 520 square feet of effective filtration area, capturing dirt, pollen, and microscopic particles down to 20 microns while providing the absolute longest intervals between cleanings of any filter in its class. Its single-piece tank is injection-molded from fiberglass-reinforced polypropylene, ensuring immense structural strength and total resistance to chemical corrosion and harsh weather. By capturing debris entirely through its massive surface area, the system eliminates the need for backwashing, preventing thousands of gallons of water and chemical waste each season. This filter features highly balanced internal hydraulics that easily support a maximum design flow rate of up to 150 gallons per minute (GPM) via its 2-inch bulkheads, making it an excellent match for high-capacity, energy-efficient variable-speed pumps. Routine maintenance is simplified by a heavy-duty tension control clamp ring with a barrel nut for rapid tank access, alongside a continuous High Flow™ internal air relief system and a convenient 1-inch bottom drain for fast winterization. The dry weight of the Pentair Clean & Clear Plus 520 Cartridge Filter is approximately 83 pounds, serving as a robust, eco-friendly, and ultra-high-performance filtration core for the most demanding aquatic environments.
