[Equipment] Phillips Dreamwear mask is whistling

[melody]

The dreamwear mask is the only mask I've found that I don't have a ton of leaks. Last night my mask started sounding like a tea kettle. The only thing I could do to stop it was to put my finger over the vent of the nasal pillows. Finally, I just had to take the mask off completely.

Has anyone else had this happen? How do you make it stop? Is there any material that can be safely used as a diffuser to put over the vent?

I found that is is a sharp edge created by the manufacturing process. Rub your finger nail over the vent a few times when it is whistling and you can normally stop it. (scraping it should remove the sharp edges).

You have little droplets of water inside. Pull it out from your face a little and flick it with your finger.
