I have a new mask now (a P20, I think?) and it exhausts through a fine mesh in the front. That diffuses the air so it doesn't blow back at you but it also creates a lot more back pressure. It also clogs easily which can really hinder exhaling. I've had a few nights where I've had to scrub the screen with a toothbrush in the middle of the night because I could barely breathe through it.

Yeesh, doesn't sound like a good solution! I used the most popular pillow type of mask, which was far superior to the old jet pilot mask, but I still never was able to sleep more than two hrs before I woke up in a sweat.
