just thinking

If there are so many mouthbreathers why dont they have a mask only for your mouth. That way you can buy a 2.00 nose plug and be done with the whole issue. I dislike waking 5x a night to correct my full face mask leaks. I will not tape my mouth shut, but a nose plug is easy and cheap. Any input

Or if you don't like that one maybe you could modify a Hybrid or a Liberty by removing/plugging the nasal pillows.

There are such things made, as noted above. Here's another one

I've seen the devices referred to as OPAP, which is actually not remotely correct, since you're replacing "Continuous" with "Oral", but hey, whatever works for them.

I have not tried the above device and have considered plugging my Universal Hybrid nasal pillows as a test, but the biggest obstacle I see is "chipmunk face" because the rush of air will make your cheeks puff out. Depending on the pressure your machine is set at, I can see the pressure causing a stretching pain on the cheeks.
