Still At It , Mixed Results

The fact that the leak rate is high while using a full face mask indicates your mask is not fitted properly.

How do you sleep?  Are you awakened by the sound of leaking?  
What position do you sleep in... back, side or stomach?  

Have you read the mask primer?

I assume the mask fit is poor...

I primarily sleep on my left side, a very small amount of time on back or right side, never on stomach.

I am awakened by one of three things: (1) rush air, (2) "farting" mask seal, (3) sensation of lack of air.

No I don't recall reading the mask primer, but I will.

Hi Brian,
I had a lot of trouble with my FFM when I started.  Then I tried the Fisher&Paykel Simplus, after reading about it on this forum.  That was about 6 years ago, and I've been happy with it ever since.  F&P also has a new FFM called the Vitera, quite similar to the Simplus, with a few updates.  Either might be worth a try for you.  There is a sizing guide .pdf document available, and the sizes of the 2 masks are the same.
