Shake off the summer heat in a cool pool. Make a splash in the cleanest swimming pool in the neighborhood with this 12-pack of Unicel C-4326 Replacement Filter Cartridges. Featuring 3-ounce basis weight and 25-square feet of media made of 100-percent polyester Reemay material, this pool and spa cartridge filter ensures high performance and dependable filtration over time. The uniform pleats and Reemay media deliver higher dirt-holding capacity and more time between cleanings. Plus, the smooth surface of the media makes it easy to maintain, resists degradation from chemicals, stands strong under pressure, and holds up to the rigors of multiple cleanings. For optimal lifespan, clean the elements as per instructions and use a soft brush cleaning tool or filter cleaner for easy maintenance. Please note that the cartridge life depends on routine maintenance and pool or spa water chemistry. Change your 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. The end caps are made of durable plastic that resists damage from chemicals and include a 2-1/8-inch ID and open configuration for easy removal and replacement. The C-4326 model of pool filters is compatible with various swimming pools and hot tubs including Hot Springs Spas, Nordic Hot Tubs, Pentair Pool Products, Rainbow Plastics, Waterway Plastics, Custom Molded Products, Coleman Spas, Beachcomber, and more.
