It is the first Water Ionizer in the world that has BioStone/Tourmaline , which generates negative-ions as soon as it makes contact with water. It activates water to assist in support of our metabolism, and circulation of blood. It also assists with skin diseases and actually helps to increase metabolism though better conductivity. In addition, Tourmaline generates FIR that enlarges capillaries, purifies water, and acts like a ‘supercharger’, assisting the water alkalizer to ionize and alkalize.
