You can use the ResMed AirMini with any mask, provided you purchase an adapter that runs @ $20. The AirMini also has a bed mount system to allow you to secure it. These small machines will fly off a nightstand if not secured because they are so light. I've traveled extensively with my AirMini and my ONLY gripe is that ResMed's app won't track two machines. The app will track your home CPAP or your travel CPAP, but not both. It's annoying.

30db is still loud.. WOuld need to sandbag the CPAP to get it to sound like a fan.
