Pentair Quad D.E.® 100 Sq. Ft. Cartridge Style Pool Filter 188594 – Premium In-Ground Pool Filtration

Sale price$0.00

Dimensions: 21.5" Diameter × 45" Height

The Pentair Quad D.E.® 100 Sq. Ft. Cartridge Style Pool Filter 188594 combines the superior water clarity of diatomaceous earth (D.E.) filtration with the convenience of cartridge-style maintenance. Designed for residential in-ground swimming pools, the Quad D.E. filter captures particles as small as 5 microns, producing exceptionally clear, sparkling water while providing high flow rates and extended cleaning intervals.

Unlike traditional D.E. filters, the Quad D.E. features four large-capacity, easily removable cartridges coated with D.E. media, providing significantly greater filtration surface area and dirt-holding capacity. Its innovative internal flow path maximizes filtration efficiency while the fiberglass-reinforced polypropylene tank delivers exceptional durability and corrosion resistance for years of dependable operation.

Engineered for easy maintenance, the Quad D.E. allows users to backwash like a conventional D.E. filter or simply remove and rinse the cartridge elements when deeper cleaning is required. A High Flow™ manual air relief valve, continuous internal air relief system, and large 1½-inch drain simplify servicing while maintaining efficient filtration performance.
