The water cannot really be bottled because it looses its cleaning properties after 18 hours I believe.
They sell small units from 1000 to 5000 for peoples homes. The units make both Ionized Acid Water and Ionized Alkaline Water (aka kangan water or alkaline reduced water). The acid water made at a persons home can be used effectively for cleaning.
The Ionized Alkaline Water has health benefits proven by many peer reviewed studies conducted in Japan and Korea. Unfortunately almost no clinical studies have not been done in North America yet on the health benefits of the water, however from the growing usage of these products in NA I am sure more studies are going to happen soon.
