ResMed F40 mask questions?

[Big Guy]

I've had good results having more than just one mask on hand. It helps me to be able to swap masks out as I feel the need. I typically use one mask for a few weeks. Once I tire of it, I switch to another. That helps to break up the monotony some.

Funny you should ask about the Evora. While it was a better fit, I've still been having leak problems and they are worsening. I need to fasten the straps so tight they leave marks. I'm going to have to try something else and have a call into my sleep therapist.

I started using the F40 mask 3 weeks ago and would fight you for it if you tried to take it away. I have been on CPAP or BPAP for 25-30 years and am now on the ResMed AirCurve 10 ASV along with the F40 mask. I don't think I have ever slept better in my life!

I gave up on the F40. Ended up being way too tight on my upper lip, affecting my bite, despite adjusting all straps. Now going to try Dreamwear full face (which is a hybrid). How do you find being on an ASV compared with apap and bipap? They want me to go back to the sleep lab (3rd time) to try an ASV; I could not tolerate bipap at lab sleep study. I had gone back to using the Evora for now.
