No tips, but I've noticed that higher humidity in a cooler room (A/C air) has pumped water into my hooter (when I use the nasal pillows or mask). Made my third overnight test pure misery, and gave me a two-day dose of sinusitis another night.

I have yet to see any bloody benefit from the air-assist. Frankly, I feel as though I can sleep better OFF the dam' machine. (When on it, I'm 12/8 with a 3 setting for humidity).

Hey Fred...
I live in a pretty dry clime area (Southern California) so my experience with humidity is rather limited.

What about the humidity keeps you up at night? Is it physical discomfort (in general) or an issue with your BiPap or mask? And how does the humidity setting help offset the condition? Sorry for the questions. Not grilling youa t all. I am rather unfamiliar with humidity issues and just trying to understand a bit more.

In the meantime, my experience witih humidity is limited but goes like this:
I once went to a summer camp type facility in Maryland near the summer and it was warm, MUCH more humid than SoCal and there was no air conditioning or fan to speak of. I felt like my face was sweaty the whole night and air just kept leaking out of my mask. I use a full face mask so it was a real bear.

Also, last summer in SoCal we had much more monsoonal type moisture around for a relatively extended period. It was rather warm and humid for a bit. I felt similar problems (like in Maryland) at night as well and all I could do was blow a fan and run the ac a bit (to de-humidify the air a bit). Once the morning arrived and it got warm and I got warm, sleep was pretty much over for me.

Hope we can help, Fred. In the least, we feel your pain.
