This is the ONLY Hybrid Alkaline Water Ionizer in the world! It is a 'hybrid' because you can either connect to your tap line or pour water DIRECTLY into the ionizer to be ionized and alkalized IMMEDIATELY, ANYWHERE. This machine makes VERY strong alkaline, ionized water with high pH and low O.R.P. (Oxidation Reduction Potential, which = Antioxidant!). You can SEE the hydroxyl ions (tiny hydrogen bubbles) in the water! https://www.youtube.com/watch?v=V8xMD-X1cnc.
