Featuring 45 square feet of 3-ounce basis weight media made of 100-percent polyester Reemay material, this 2-pack of Unicel 6CH-940 Cartridge Filters for Hot Tubs 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 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 top load end cap is made of durable plastic that resists damage from chemicals and includes an injection molded 1.5-inch SAE thread and a semi-circular handle for easy removal and replacement. The 6CH-940 model of spa filters is compatible with Catalina Spas, Charisma Spas, Leisure Bay Spas, Waterway Plastics, Custom Molded Products, Bullfrog Spas, Dynasty Spas, Sunrise Spas, Master Spas, and more. This 2-pack of Unicel 6CH-940 Spa Cartridges Filter is clearly the optimal choice to keep your hot tub or spa water sparkling.
