Test result comes, haha! You won't believe he was in the mask for a whole night. And the first part I set the auto-adjust mode, and it just like rested gal said,"5 feels like nothing." I believe because he is normal so the 5-15 range always stayed around 5. So the latter part, set to CPAP mode at 12...

A friend of mine was curious that how I sleep every night with that mask and a breathing machine. He wants to try it on. Any idea on it? I would like to know if it is harmful to a normal guy who doesn't have our problem when he breathes through the mask with pressure set from 5-15 for like 4 hours. ...

Hi, now it is summer. How many of us here still turn on the heated Humidifier? If yes, set to high or low?

thanks!
