High-performance polyester extends the cartridge's lifespan compared to lower-cost alternatives. Increased pleat count enhances filtration capacity. The Trilobal fabric structure facilitates easier removal of contaminants during cleaning, allowing the filter to perform like new after washing. It is recommended to clean the cartridge every two weeks to maintain optimal spa performance. This spa filter offers lower pressure drop and higher flow rates, reducing pump wear and energy consumption, contributing to longer product life. Long lifespan design features thickened filter cloth, heavy-duty anti-chlorine end caps resistant to breakage, a reinforced center core, and durable washable pleated fabric for extended use and reusability. Effectively filters hair, leaves, sand, stones, dust, impurities, and sediments with high efficiency. Color: White. Material: Plastic. Size: 125 x 335mm. Package includes: 1 x Spa Filter.
