Mirage Micro Whistling

[Mike77]

I swapped masks last evening from the Swift LT to the Mirage Micro and I had the best night of sleep that I have had in years! However, my better-half complained that the Micro was making a high-pitched whistle all evening. I checked for leaks around the seal and there were none. It seemed as though the whistle was coming from the area of the mask where the hose and elbow attach to the mask proper. I checked the mask this morning and there are no cracks or ill-fitting pieces that I could see. Has anyone else had this problem? Does anyone have any suggestions for ways that I can fix the issue?

I am thrilled that I was able to sleep - now if I could only make it bearable for the others in my home...

I don't know the mask but you can put either teflon plumber tape or paper first aid tape to help seal the connection and see if that helps. Of course, make sure the exhaust vents are not affected.

I used paper first aid tape on all the connections on my old swift; others used teflon tape.

Mine did that for awhile, but stopped. Don't know what caused it, but I know it was coming from the exhaust vents....Sometimes it will start in the middle of the night if the vents get blocked by moisture or such, I "tap" them and it stops.

Problem solved... I rushed home from work early to tinker with the mask and solved the problem. It looks as though the silicone part of the mask was not seated correctly on the plastic part of the mask. There was a tiny knob of silicone on the seal that caused an ever-so-tiny leak. With a steady hand and a pair of cuticle scissors, I cut off the knob and tried the mask again.

Lesson learned! Thanks again for the feedback!
