Pleated Filter Cartridges Our Universal Pleated Filter Cartridges are washable, reusable, and durable. As a result, our filters last longer than other brands, and are more economical too. Our filters work hard for you by holding more dirt than other brands; and increased dirt holding capacity means cleaning your pool or spa less often. Our universal pleated filter cartridges are constructed of the highest quality non-woven polyester, with a durable polypropylene core to provide maximum strength. The ends are immersed in thermo setting vinyl plastisol that seals the end of each pleat uniting the components and forming a permanent bonded end cap, unlike cheap alternatives. This makes our universal pleated filter cartridges perfect for residential, commercial, and industrial pool and spa applications.Relish our comprehensive pool and spa collection that includes world-class filters and state-of-the-art pool, spa, and pond accessories at exclusive discount club prices.
