Featuring 25 square feet of 3-ounce basis weight media made of 100-percent polyester Reemay material, this 2-pack of Unicel 4CH-24 Cartridge Filters 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 a 1.5-inch male thread/MPT and molded cone handle for easy removal and replacement.

The 4CH-24 model of spa filters is compatible with various hot tubs including Advanced Spa Design, LA Spas, Lowes, Saratoga Spas, Dream Maker Spas, and more.

This 2-pack of Unicel 4CH-24 Spa Cartridge Filters is clearly the optimal choice to keep your hot tub or spa water sparkling.
