Love my P10 mask. Hate the small and limited headgear. Previously tried to rig a P10 using SwiftFX headgear with moderate success, but I hate doing that each time. Pressure is IPAP 9 and EPAP 6. Sometimes the pressure blows my soft palate around and makes me choke awake, but not that often. AHI is below 1 now. I get tangled in my hose. I run it under my pillow and limit its length that way.
I have previously had the P30i. When I tried that with my bilevel, it is SO loud with the air rushing past my ears. Love the over-the head squivel ability of the P30i, though.
I also breathe out of my mouth sometimes all throughout the night and wake myself up. In the past, I've mouth taped and it was pretty uncomfortable/caused panic attacks. Tried a Dreamwear nasal and full face mask...didn't like either. The FFM made my cheeks puff in and out with the flow. Chin strap didn't work.
