Distilled water has less minerals, of course, but I can't imagine how it is less likely to have germs. Surely that depends on how clean the bottling line is, how old the bottle of distilled water is, etc., etc., etc. I doubt that your rebottled distilled water has a significantly lower bacterial load than a unopened small bottle of "spring water." Even the difference in mineral content is probably minimal, since most bottled water I have tried is very soft.If you're using bottled water for your CPAP, you're using the wrong water. Safest and best to use distilled water. No chemicals. less likely to have germs, safest to inhale.
What both will have is a lack of the chlorine smell that tap water can have, and which I find unpleasant.
