AirFit F30i - Frame

Very, very good system with excellent comfort and strong tendency to stay put through the night even on this side-sleeper who turns to the other side without awareness. I get great therapy results with this, without the annoyance of a mask over the bridge of my nose or a hose in front of me to tangle with. Comfort on the face is outstanding, hose stays out of the way. Combines the superior comfort of a "nasal pillow" with the dependable pressure delivery of a "full face" mask.

Downsides:

Some tendency toward irritation where the straps graze the skin closest to my neck—if the straps are tight enough to get a good seal under the relatively high ~14-17 inHg pressure I usually need, they are tight enough to irritate by morning in the back. The front-facing vent holes can be annoying now and then, for example by blowing on my spouse or bouncing off my phone or book back into my eyes while doing some reading before falling asleep. The top-of-head part that makes this headgear so great for side sleepers leaves its impression in one's hair, and this seems worst for short hair. If your hair is long enough to be swept back by the headgear, or you have a buzz cut, you should be fine, but you may need extra grooming effort in the morning if in-between.

I like this mask. But after only 1.5 months, the little tiny tabs that clip in the Anti-Asphyxia valve on the right side broke. I can still wear the mask, because the strap pulls it back and holds it in place when it's on. But it's always falling off when I take it off. Another review shows pics of what I'm talking about.. And nobody sells just that 5 cent piece of plastic.. You have to buy a replacement mask.
