i have anew 431 just got it. The whistling all night long keeps me awake also. I can not wear it. Did anyone find a way to stop the air leak? Help!

I been using F&P FF #431 and #432 for all year 2011 and loused up on my treatment b/c of leaks. These masks don't use the technology of double silicone flaps in their cushions and thus can't seal effectively. Switching to my present mask and chinstrap (see below) in early 2012 has saved my life regarding treatment with envious results. NO MORE LEAKS. During the last two years I ran across about a dozen posters, on this board, who swore that one of those masks "WORKS" for them. However, they never presented a leak graph to validate their words. Just words, words, words.............

First, make sure the cushion is fully inserted all the way around.
Second, the mask design does not cover a large range of face shapes.
If it does not fit your face, it never will.
If it is comfortable and seems to seal, you can try loosening the straps, using air pressure to fill the cushion.
as too tight a cushion will make creases--thence leaking.
Try to eliminate the creases; use a mirror; and wash your face.
A clean face is a sticky face. The same with silicone.
I even put a smear of Lansinoh all around one mask, so it would stick-
