Flow rate: 1 GPM Cartridge is designed for use in Under Sink Filtration & Reverse Osmosis Applications 3RD STAGE: GAC10" ACTIVATED CARBONGAC Filter Cartridge (UDF-10) is granular activated carbon (GAC) coconut shell water filter replacement cartridge used to reduce the bad taste and odor of chlorine in a variety of low-flow applications such as under sink, countertop, and pre/post-reverse osmosis water filtration systems. This filter may also be used in some humidifying systems, recreational vehicle filtration systems, and food service applications.The UDF-10 carbon filter features coconut shell granular activated carbon (GAC) technology for more advanced water filtration, maximum chlorine absorption, and better tasting water. The coconut shell GAC design of these filters are some of the most effective water filtration media for the reduction of organic compounds such as chlorine, VOCs, radon, and other impurities. They are axial flow filters, meaning they are designed to force water to pass through the entire carbon filter media in order to ensure thorough filtration.4TH STAGE: MEMBRANE 75 gallons per day. 5th STAGE: INLINE CARBON FILTER- for taste and odor regulationClick here for INSTRUCTION MANUAL
