Using a patented two-stage cartridge, this shower filter neutralizes the harsh effects of chlorine and other impurities in tap water, leaving your skin feeling softer and your hair looking fuller and more lustrous. In the filter's first stage, Kinetic Degradation Fluxion (KDF) granules restore water's pH balance and remove up to 99% of chlorine that can strip your body's natural oils, resulting in dry skin and brittle hair. Its second stage uses carbonized coconut particles to remove chemicals and volatile organic compounds (VOCs) that can be absorbed through the skin. The filter installs easily and will not affect water pressure, whether it is used with your existing showerhead or with the included adjustable-massage showerhead. The cartridge filter lasts for up to six months. 9" L x 3" W x 3" D (2 1/2 lbs.)
