I bought a new Cpap the other day and decided to follow the instructions this time and use distilled water because my other Cpap gets a lot of scale build up in the tank. So I used it for a week with the distilled water and ended up with a bad skin irritation (almost like really bad chapped) around my nose. SOOO I go buy a new mask thinking that's the problem, no dice. I tried my old machine with the distilled water and same irritation. The only thing I can come up with is that the distilled water is causing it so I'm going back to tap water (well water) to see if that is the problem because that is the only thing that has changed. Can't figure out why distilled water would cause it because it's suppose to have all the impurities removed. Anyone else had a problem similar?
