The Vevor pool filter cartridge set includes four 130 sq. ft filter cartridges designed for pool and spa filtration systems. Built with trilobal high-efficiency filtration fiber, these cartridges help capture hair, leaves, dust, debris, and other fine particles for cleaner water. Their high-permeability structure supports steady water flow while reducing resistance for efficient pump operation. Reinforced end caps and a durable center support structure add strength for long-term use. The cartridges are also easy to clean with a quick rinse for simple maintenance.
