The Nu-Plus CFS water filtration systems come in the following head configurations:
Filter capabilities consist of the reduction of sediment particulate as well as chlorine and other objectionable taste and odors of the water which would adversely affect the taste of carbonated and non-carbonated beverages, coffee and ice. Also, a food-grade scale and corrosion inhibitor can be automatically fed into the water to inhibit the formation of scale in ice machines and coffee makers. Nu-Plus CFS filters have been tested by the manufacturer against ANSI/NSF Standard 53 for the reduction of chlorine taste and odor.
