They use zinc and copper as a part of their filtration process, which results in natural, simple, long-lasting performance. Copper and zinc effectively remove all impurities, including chlorine and heavy metals while also averting bacterial growth

An added step to their filtration process is the use of coconut-shell carbon in their drinking water filters to remove VOCs, organic waste particles. It also helps to enhance the taste of the water.
