Need new filters for your Hayward Swim Clear pool filter? This 4-pack from Optimum Pool Technologies is the perfect match. These cartridges are 25.5 inches long, with a 7-inch outer diameter and a 3-inch inner hole. They're made in the USA with durable Reemay filter media and have support bands to keep their shape. They're direct replacements for a bunch of part numbers, including the Hayward CX875XRE, Unicel C-7489, Filbur FC-1275, and Pleatco PA112. Basically, if you have a C4500 or C4520 filter, these should fit right in. They're built to be cleaned and reused, making pool maintenance a bit easier. Just remember, these are high-quality aftermarket parts, not the original Hayward brand.
