Been on bipap for about 12 years now. Humidity set at about 3 out of 4 on machine . Use nasal pillow and chin strap . We put a folded faceclothe under the chin part and pull this part up under the lower lip. It needs to pull in on lip. Have to keep lips closed to prevent air escaping . Otherwise get dry and sore pharynx. Also need to tip my head forward a bit with another small pillow under the top part of the back of my head . Tried full face mask but couldn't talk with it on and found it would always start leaking after a few hours and I am quadriplegic and needed my wife to wake up. Tried tape for a while but can't talk with tape on either .
