A clean cartridge is the easiest way to keep pool and spa water clear. We carry replacement filter cartridges from Unicel, Pleatco, Filbur and OEM brands to fit Hayward, Pentair, Jandy, Sta-Rite, Waterway, Intex and most hot tub filters, plus DE and filter media.
To find the right cartridge, match the part number on your current filter (such as C-7490 or PA137) or measure its length, outer diameter and top and bottom openings. Rinse cartridges regularly, soak them in a filter cleaner a few times a season, and replace them every one to two years.
