After using my AirSence 10 for about a year, it stated to make noise

It stared making significantly more noise at night. Exhaling sounds about the same, but when I inhale, it is much louder! I’m constantly waking up now because of the sound of my inhaling. My wife noticed it too. I have been shutting it off in the middle of the night just to get some uninterrupted sleep. Can it be repaired??
