I have a question about eliminating a persistent sour+plastic smell coming from my ResMed AirCurve 10 ASV. I cleaned the pipe and mask yesterday, and just to confirm that the smell wasn’t coming from either of those. The smell is coming directly from the inside of the hole that comes from the ASV into the water container. Let me show you what I mean in this link (2nd Picture), posting pictures here often doesn’t work:
So in what ways could I clean the machine out to eliminate the scent itself?
