Now the latest filter pitcher technology comes in a sleek design. This 8-Cup Stainless Steel Pitcher implements ZeroWater's five-stage filtration system to remove virtually all dissolved solids from your tap water and deliver you great-tasting water in just minutes. The pitcher comes with one Ion Exchange filter, a laboratory-grade testing metre, and a guarantee to remove virtually all dissolved solids from your drinking water. ZeroWater's Ion Exchange filter works in five stages. The primary layer consists of activated carbon and oxidation reduction alloy, which removes the chlorine taste you are accustomed to in your tap water. Next, the Ion Exchange stage removes virtually all dissolved solids, such as Aluminium, Lead, ZInc. and Nitrate, that may be left over from public water systems or even leached into your water from piping. The following three stages are included to ensure your water receives the appropriate amount of treatment time to deliver a "000ppmâ€ reading on the included laboratory-grade Todal Dissolved Solids metre.
