Unicel C-8399 Replacement 100 Sq Ft Hot Tub Spa Filter Cartridge, 259 Pleats

Featuring 100 square feet of 3-ounce basis weight media made of 100-percent polyester Reemay material, this C-8399 Cartridge Filter 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 end caps are made of durable plastic that resists damage from chemicals and include a 3-5/8-inch ID, open configuration (with lip seal), and semi-circular handle for easy removal and replacement. This C-8399 model of spa filters is compatible with Caldera Spas.

The Unicel C-8399 Cartridge Hot Tub Filter is clearly the optimal choice to keep your hot tub water sparkling.
