Perfect for residential and commercial ice makers as well as refrigerators, drinking fountains, coffee and tea brewers, motor homes and campers. This filter reduces chlorine taste and odors and filters up to 20,000 gallons.


Uses a KDF Fluid Treatment for filtration. Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc formulation that uses a basic chemical process known as redox (oxidation/reduction) to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor) and chlorine. KDF Process Media are generally used in place of, or in conjunction with, GAC (Granular Activated Carbon) filters, carbon blocks or inline filters. KDF Process Media helps to extend the life of GAC carbon.
