http://www.lifeionizers.com  -  The two leading brands of water ionizer sold today are LIFE Ionizers® and Enagic's Kangen®. These two companies out-sell all others combined. Enagic's Kangen® has never updated the technology in their ionizers, where LIFE Ionizers® comes out with some kind of new technology or refinement every year. Technology makes a huge difference; the LIFE Ionizers® machine can make alkaline and acidic water straight from your tap, the Enagic's Kangen® machine needs chemical additives to produce its full range of alkaline and acidic waters.
