I have a Mirage Swift; after a week's initial adjustment, I love it. My husband, however, is not so happy, since the Swift blows air on his face. I went back to my old Ultra Mirage nasal mask; after the Swift, the Ultra Mirage is only so-so: heavy with a few leaks. It's funny that I liked the Ultra Mirage quite a bit until I tried the Swift, but now don't like going back to it.
Has anybody overcome the Mirage Swift's exhilation port problem successfully?
