Purified water

Properly maintained and functioning RO water from your fridge, assuming a clean "post" filter in your fridge doesn't contaminate the product water from your unit (assuming the unit is operating at an acceptable rejection rate and TDS levels are acceptable, the system has been sanitized and maintained properly) will be fine.


There is a lot of snake oil and misinformation out there, but having been ceritified (albeit long ago) with the Water Quality Association ( http://www.wqa.org ), I have seen this type of conversation many times.

RO water is very good and can be just as pure as distilled. A TDS of 20 is very low. There is nothing wrong with drinking very pure H2O. You should not be relying on impure water for your trace minerals. Try eating good food for that. I, too, have heard this discussion many times and have to wonder how the "pure water leaches the minerals" fallacy even got so prevalent in the first place. It's true that it can, but not in a normal body. I and my family drink RO-DI (de-ionized) water and have for many years. This is more pure than distilled. I water the houseplants with it as it doesn't spot leaves or crust the soil. I fill the fish tanks with it. I make coffee and tea with it because it doesn't crust up the pots. I use it in my humidors. I top off batteries with it. I never have to wonder what's in it.
