Aqualite PP20M20BB polypropylene string-wound cartridge removes large particles such as sand, rust, silt, and clay from the water. Its tightly wound thread forms a strong, layered structure that gradually traps impurities while letting only clean water pass through. It’s the first step in protecting your entire filtration system from premature wear and tear.
