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. ZeroWater filters are also the only pour-through filters on the market certified by the NSF to reduce lead. This 23-cup system comes with the largest capacity filter dispenser on the market today, our patented Ion Exchange filter, a laboratory-grade water testing meter, and a guarantee to remove virtually all dissolved solids from your tap water. ZeroWater also removes 99% of Fluoride from tap water. ZeroWater\'s first layer of filtration, activated carbon and oxidation reduction alloy removes the chlorine taste you are accustomed 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 Aluminium, 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 laboratory-grade Total Dissolved Solids meter included.
