After long and I mean a very long research....I've decided NOT to drink RO water, sure, in areas where water is truly an issue/problem RO is the best method to get rid of bad elements. I recently bought a RO/DI unit mainly for my fishtank, but since it came with a container tank and a faucet, I said "what the hell" I could bypass the DI part and have fresh purified RO only water to drink....According to many doctors and even the World Health Organization, drinking RO water or even worse, distilled or DI water can have long term negative health effects on the human body. Water with <75 TDS can seriously affect your intestinal track, and the lack or low level of minerals can cause other health problems, etc. Check this link and you be the judge, http://www.who.int/water_sanitation_health/dwq/nutdemineralized.pdf This is just one of the many articles I've found and that for now, has changed my mind, I'll stick to my snap-on filter (carbon) to remove chlorine and odors and leave the RO and DI for my aquarium water changes/salt mixing. If you find a better article or one that contradicts the "health risks" that RO can represent to humans, please share it, I'd like to see it.
