Zeta is offering a family of water systems that gives ordinary tap water a negative charge and allows the user to choose the pH level of the water coming out of their tap. Zeta"s systems generate what is referred to as oxidation reduction potential (-ORP). The ORP properties of Zeta alkaline water are known by many as "antioxidants". Normal body functions cause high or rising oxidation inthe body, which is not good. To fight against oxidation, the ORP charge given by Zeta"s water systems literally hinder the oxidation process by counteracting any rising oxidation effect in the water.These systems are KFDA registered as Class 3 medical devices and registered with the FDA as class 1 medical devices. They are among the highest end alkalizers on the market and priced very competitively.FEATURES - All Features from ZWS2020, PLUS:? 7 Platinum-Titanium Plates?
