take a little getting used to and many people quit before they push through the getting used to it part. Sadly, a couple of people I know that quit have died in their sleep (probably related though I don’t know).

The difference for me has been enormous.

I started out using a nasal cushion that I like. The problem is it blew cold air directly out from my face and was annoying for my wife. So I switched to a full face mask and that problem was solved.

If you’re worried about noise, they have become much more quiet over the last several years.
