Just to make sure I am thorough in my exploration of options. I ordered a F20 Airtouch Full Face Mask. I have had bad results with FFM because I have a full long beard. I was hoping the resmed ads showing it working with beards wasn't all hype.
I do so love my P10 but to absolutely get leaks down to single digits or zero, I need to use a chin strap/cervical collar because my mouth opens up. Not really a mouth breather but still. I haven't had success with chin straps (yet) and the cervical collar isn't bad but I am not a fan.
I got the F20 Air Touch to pass that mask fit screen and here is my first full night with mask. My only complaint is that I found it difficult to breath through my nose with the mask on. I ended up breathing through my mouth and it got a bit dry. Not like with it opening when doing the p10. I upped the humidity and temp we'll see how that goes. The difficulty may just be from the added pressure across the bridge of my nose.
My original intent was to have a solid backup in the even cold or something. Turns out it was a lot more comfortable than I thought it would be.
It's a wash between bulky face mask vs pillow mask + cervical collar in terms of which is more intrusive.
I was aroused only once though and that was at my normal ~6 hour mark which is when I wake up feeling fully refreshed typically. So subjectively, my sleep was really good with the F20.
I have found that my pressures are "higher" with both cervical collar and this mask. I know that most of my apena happened during REM according to my sleep study. Just conjecture on my part but I am fairly certain that the higher pressures are due to me sleeping deeper and not being aroused by the tornado coming out of my mouth when it flops open so sleeping deeper is a WIN for sure.
Here's the chart for the data hounds.
