Features

4 PREMIUM FILTERS: SED sediment filter reduces large particles to protect the other cartridges. CB carbon filter uses coconut shell solid block activated carbon to protect the RO membrane from chlorine and other chemicals. RO reverse osmosis membrane reduces particulates and impurities in water down to 0.0001 micron, including total dissolved solids (TDS), heavy metals, sodium chloride, copper, chromium, lead, and more. The last stage is a DI deionization filter for further reduction of TDS.
DEIONIZATION FILTRATION: A fourth stage DI cartridge employs a mixed-bed, indicator resin for enhanced filtration of TDS (total dissolved solids). A 2:3 ratio of cation and anion resins assists in near complete reduction of ions from water including sodium, sulfate, copper, and more. Color-changing green media turns purple when exhausted, letting you know it’s time for a cartridge changeout. Deionization produces pure water faster, more efficiently, and more affordably than distillation.
