I did see the first link, I disagree with the second link as well. Drinking water isn't just filtered tap water, it is usually spring water which doesn't have any of the added junk like chlorine and chloramines. Distilled water and R/O are also different as Bill stated before. One other thing I noticed is the age of that article, some of the original content is from 1997 by Frank Indiviglio, don't get me wrong as Frank is an awesome guy... I just feel that some of the information on that article is outdated a bit.
