How come none of the masks worked?

I was fully prepared to have to go through the entire gamut of masks to find one that worked, because I snore so surely I would need a mask that covers my mouth at least, right?

But even while sleeping, my brain is keeping my mouth shut so the simplest, nose-only mask works perfectly, with very little leakage.

What was your severity of sleep apnea? Do you mind sharing your AHI?

Have you tested it with a polysomnography?
