Unicel Cartridge Pool Filter 80-sq ft

Cartridge Pool Filter 80-sq ft. Pack of 4 replacement C-7470 pool filter cartridges ensures your water stays clear so you can enjoy relaxing in your swimming pool. Features 80 square feet (170 pleats) of 4-ounce basis weight media that catch debris and particles down to an average of 20 microns in size. Sharp, uniform pleat folds maximize water flow, minimize pressure loss, and allow full use of the pleat surface to hold more debris. Constructed with 100-percent polyester Reemay material that balances dirt-holding capacity, cleanability, and durability with excellent chemical resistance properties. End cap design includes a 3-inch ID and an open configuration for easy cartridge removal and replacement. Durable end caps resist damage from chemicals and assure durability for the life of the cartridge. Compatible with Pentair Pool Products, Pac Fab, and Waterway. Filter life depends on routine maintenance of water chemistry. Change filter when there is a shorter cycle between cleaning, low water flow rate or high differential pressure, when the media has a tear, or if the center core collapses
