I've been using my Airsense 10 for about a 1 1/2 years. I've had no problems with it until a few weeks ago. As soon as I would turn it on, it would blow too much air. Turning it off and back on would fix the problem. Well, now turning it off and on doesn't help. Last night the air was so annoying and loud I had to not use the machine so I could go to sleep. Is my machine broken or is there something I can do to get it back to normal?
