Last week I picked up a ResMed Quatro FX - a relatively new model and of the
five masks I had previously, this one fits the best and leaks the least. I
won't use the nasal mask ever again. The new one is the most comfortable
mask I've used. I may go back and see if I can get a better adjustment on
the straps as it likes to slide up my nose during the night and it isn't
supposed to. But other than that - if I have to sleep with a mask, I'll
take this one.
