ZeroWater water filters utilize a patented 5 stage Ion Exchange system that removes 100% of detectable dissolved solids and provides more complete filtration than conventional carbon water filters. ZeroWater is the ONLY filtered water that meets the FDA definition for purified bottled water. In side by side tests, ZeroWater scores a perfect 000 for detectable dissolved solids as measured by a TDS meter. Products include pitcher water filters, cooler systems, replacement water filter cartridges and laboratory grade TDS meters. * Filtered potable tap water tested by an independent lab (not the FDA) to meet specifically the water quality requirements for using the label "purified." †Compared to water produced by leading gravity fed filters.
