Additionally, a very beneficial thing a water ionizer does is to make your water WETTER. Water tends to cluster itself with other water molecules. After making its way to your city's water treatment facility, and sitting in storage, it is "treated". The treatment plant adds chemicals to increase the alkalinity of your water, kill germs, and so forth. Finally when it arrives at your tap, it is full of chemicals and is also found to be in much larger cluster-sizes (13 or so molecules per cluster). Your water ionizer splits those large water clusters in half, making them smaller and more easily absorbable by your body. So, an additional benefit of the water ionization process is that the water you drink will hydrate your cells far better than any other water can do.
