Used the F30 for 3 nights and that convinced me it is the best for me.
It took three nights to convince me that the F30 is the best for me. For 7 years I used a nasal mask, then eventually I couldn't keep my mouth closed at night, even with a chin strap. So I then used the F20 for nose and mouth coverage for 3 years. That worked better but dry mouth increased. The F30 is more comfortable, and takes more care to position properly but it's worth it. Using heated tubing, Airsense 10, with SoClean.
