ZeroWater is a water filtration system designed to remove impurities from tap water. It uses a five-stage filtration process, which includes activated carbon and ion exchange technology, to reduce contaminants such as lead, chlorine, and other dissolved solids. The result is cleaner, better-tasting water. The ZeroWater pitcher comes with a built-in TDS (Total Dissolved Solids) meter, allowing users to measure the purity of their water. This feature helps ensure that the filtration process is effective and provides a clear indication of when the filter needs to be replaced for optimal performance.
