Enjoy the clarity and quality of your cold therapy experience with our specialized replacement filter cartridge, designed to fit most standard 10-inch housings found in cold plunge tubs, plunge pools, and other water systems. Its 20-micron filtration level effectively captures fine particulates like sediment and rust, contributing to visibly cleaner water. Built with a robust pleated design and a reinforcing mesh for enhanced performance, this cartridge supports easy maintenance and is suggested for replacement every four to eight weeks based on usage. Installation is quick and easy:  twist the housing cap counterclockwise to open, swap the old cartridge for the new, and securely fasten the cap back in place, a process that takes just moments to complete.
