Darn right its convenience is debatable.palerider wrote: ↑Sat Mar 23, 2019 12:38 pmNo, Any water that's safe to drink, not just distilled.
Distilled water is a *convenience* (debatable one, since you have to buy extra water and carry it around, or buy a distiller), but if that is less trouble than having to descale your water tank now and then, then it's a convenience.
But it's not *necessary*
Some water systems water is so soft even mineral build up is negligible.
When I first started CPAP, I used only distilled because I ignorantly believed it was medically necessary. I then learned it wasn't many of the sources were Palerider's links to studies demonstrating that bacteria is simply not transferred through humidity.
I then kept using distilled water, so I wouldn't have to waste time descaling. Without even determining for myself how necessary it was.
Finally, I decided to actually see how quickly and how prevalent the built up scale was.
It's been months since I've used distilled and I haven't had to descale. Not once. I'd also like to add that I only clean my tank one a month give or take.
I live in an area with soft water, of course others who have harder water may prefer distilled. It's worth it to them.
But cripes people, try it yourself. Draw your own conclusions, based on your experience with your water.
