Enjoy great-tasting water with next generation filter technology. The ZeroWater filtration system combines five sophisticated technologies that work together to remove virtually all dissolved solids from your tap water, delivering you great tasting water. This device uses the same filtering technology as other ZeroWater pitchers and dispensers. This 40-cup system comes with the largest Capacity filter dispenser on the market today, our premium ion exchange filter, a water quality meter, and a guarantee to remove virtually all dissolved solids from your tap water. ZeroWater first layer of filtration, activated carbon and oxidation reduction alloy removes the chlorine taste you are accustom to with tap water. The ion exchange stage removes virtually all dissolved solids that may be left over from public water systems or even leached into your water from piping such as aluminum, lead, zinc, Nitrate and more. Three additional stages are included to remove other impurities and to ensure your water receives the appropriate amount of treatment time to deliver a "000" reading on your water quality meter.
