I use an AirFit N20
I use an AirFit N20 nasal mask with AirFit cushions, and they are absolutely perfect, no complaints at all. Taking advantage of a Black Friday discount, I decided to try the AirTouch cushions. Confident in their quality, I went ahead and purchased three at once.
When I first tried one, I was impressed by the comfort and feel. However, no matter how tightly I adjusted the mask, the cushions consistently leaked at pressures above 14 on my AirSense 10 APAP machine, waking me up in the process.
ResMed customer support were excellent; they promptly issued a refund and assured me that the cushions were tested for pressures up to 30. While that may be true, it wasn’t my experience. I’m now back to using the AirFit cushions, and they remain perfect for my needs.
