Machine whining
I've noticed the last few nights my machine is making a whining noise each time I inhale. Any ideas?

RE: Machine whining
Remove and separate the humidifier, hose, and mask. Inspect for leaks/holes in all. Firmly reseat all of the above (Humidifier is the likely culprit).

Also, check the filters. They should be routinely changed at least once a month.
I always pick the 1st of each month and change them, wipe down my machine, wash the humidifier chamber, hose, mask......

RE: Machine whining
If the noise follows the fan speed, it might be a warranty issue.

Conversely, when you exhale it spins slower. If you rule out leaks, it sounds like the blower has developed problems. I've had to replace a Dreamstation due to this issue.

RE: Machine whining
Sometimes 'flashing', bits of plastic left over from the casting/injection-molding, processes, can be in the airway or on generating surfaces. Or, a fan blade might have a sleek on its surface, or a small fracture that emits noise of a frequency as air passes over the surface. Or, our hoses aren't quite correctly seated in the mask's receptacle (happened to me).
Or it is internal to you.  Good luck with that one.
