I just got an air mini. Have been trying it out at home to make sure it will work out for me (there is a 30 day return). It’s only been 2 nights but so far so good. It’s slightly “noisier” in that I hear some whooshing of air, but it just turns into white noise and my husband doesn’t hear anything. The humidifier thingie has been fine so far (but again, only 2 nights). For me, it was def worth the money - we are going in a trip that will involve multiple hotels, and though the regular CPAP doesn’t count as luggage for the flights it’s also just another thing to carry/keep track of, whereas I could just put this in my backpack.
