ZeroWater® filters out 99.6% of all dissolved solids for the purest tasting water. Rather than filtering with a conventional 2-stage system, ZeroWater® premium 5-Stage filtration process filters out virtually all dissolved solids from your tap water including salts, lead, chemicals, fluoride, minerals and runoff. This process removes suspended solids such as dust and rust that may make water appear cloudy. It then removes organic contaminants including pesticides, herbicides, Mercury, Chlorine, Chloramine, and stops bacteria from growing.
