Featuring coconut shell granulated activated carbon (GAC) this coconut carbon filter reduces the unpleasant taste and odor of chlorine. The advanced coconut carbon filtration technology of these Whirlpool RO filters maximizes carbon capacity and maintains a low pressure drop for efficient water filtration. These reverse osmosis filters reduce waterborne contaminants such as dirt, limescale, rust, sediment, sand and silt. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before and/or after the system.
