Tried increasing pressure but no luck. Leaks were good and mask was very comfortable but just couldn't get the results using the F30, Went back to the P10 and instantly back to the old results using the old pressure setting. Just like the OP I am at a loss to explain it and just gave up. My reason to switch was to get away from a chin strap but I will live with that discomfort. I thought it might just be an adjustment period but I hated looking at the bad results. May try it again with a machine that doesn't have data so I don't see the results and then after a few weeks try my data machine again. Funny thing was I actually felt pretty good in the morning even though the results said I shouldn't. The F30 seems like a great mask but.....maybe its jinxed.
I am also trying to switch from the P10 to the F30. I was never able to solve my mouth leak problem with the P10 and dry mouth episodes were uncomfortable. AHI with the P10 was fairly good, averaging about 1.5 over the last 30 days. Leaks were low. Sleep quality was not as good as I would have liked (and I have recently been trying CBD oil to help).
I've used the F30 for about four nights so far. I'm still working with the mask adjustments, so it may get better. Loosening the top strip, effectively making the headgear larger, made the mask more comfortable. AHI is higher, from about 2.5 to 9.5! (The two nights above 9 may be related to a medication problem -- I am still trying to isolate that.) Leaks are worse than with the P10, but not often into large leak territory so the machine is handling the pressure ok. An unanticipated side effect is that aerophagia appears to be significantly reduced. Of course, mouth leaks and resulting dry mouth are no longer a problem.
The major leak problem I am experiencing is on the cheeks, I think when I relax and my mouth drops open slightly, opening a leak at the sides as the cheeks hollow out a bit. That, and the noise the leak makes, tends to wake me up.
A very surprising result is that I think I am sleeping better and waking more rested with the F30, despite any AHI and leak problems. We'll see if that holds up, or whether it is just the effect of trying something new.
