Also distilled water is actually like an antiseptic or disinfectant to some bacteria since they can't live in a pure water enviroment ("diffusion through a semi-permeable membrane" I believe keeps pumping water into the bacteria until they explode in some cases).Gerald wrote:Randy.....
I respectfully disagree with your position on "distilled water". At home, I do use distilled water....but on a trip I don't want the hassle of trying to find some while I'm on the move.
I realize that the manufacturers suggest the use of distilled water....but they don't give a reason "why" they do so.
So why is distilled water recommended? Why is it better than drinking water for use in a CPAP humidifier? What principles of Physics are involved here? What can go wrong when drinking water is used? What damage will drinking water do to Hose-Head's humidifier?
if I'm missing something, I'm eager to learn. Please let us know why you believe distilled water to be imperative while Hose-Head is on his trip.

All good points. However, I'm only going to be gone for 9 nights. That doesn't give bacteria much opportunity build up.
As a seasoned traveller (but never before to Europe), my practice has been to use bottled water when traveling (NOT mineral water). Bottled water is potable and it's readily available. I discard leftovers each morning, and rinse and dry the humidifier reservoir (necessary when packing up for the day's travels). No need to carry distilled water from one day to the next because I can always find another bottle of water at the next hotel. Once home from the trip, everything is thoroughly cleaned and the humidifier is decalcified with a vinegar bath. With this regimen, I've yet to see any kind of mineral build up or growth of mold or bacteria. I've seen nothing posted in this thread (to date) to indicate that it won't work for me in Europe, too.
Thanks for you post!
