I am the procuction manager of a company that produces an all natural odor neutralizer and we start out using deionized water which goes through a series of mixed bed resin tanks to remove the impurities and an ultraviolet light as well. I was thinking about how pure the water is when it is refined and thought about the idea of drinking it, but before I did I decided to look online to find information relevant to it causing any bodily harm. The results I found were interesting enough for me to submit my idea. Check it out for yourself and I hope to see a show on this in the future. Im sure there is enough people out there drinking purified water that would be interested in watching a show about it.
