The Filbur FC-2570 Pool & Spa Filter Cartridge is a 137 square foot pool filter cartridge. This swimming pool filter is designed to be easy to use and effective. This pool filter is made with a polyester media that fights off dirt and will last for a long time. This spa filter includes a sturdy PVC Center core that makes the filter stronger, and resistant to breaking. Filbur pool and spa filters include broader support bands that allow the pleated media to produce optimum efficiency. The end caps of the FC-2570 have molded fittings so you will have no need for PAD adapters for your pool filters because these filter caps are installed and removed easily.
