The AirFit N20 features ResMed's most adaptive cushion ever, the InfinitySeal. These InfinitySeal Nasal Cushions are designed for use with all AirFit N20 & N20 For Her CPAP/BiLevel Masks.
Size Information: Infinity Seal Nasal Cushions come in three sizes -- Small, Medium & Large. All AirFit N20 and AirFit N20 For Her masks use a single frame size so any cushion size can be used on any mask frame. If you would like to change the size of your mask, you can just purchase a different cushion size and fit it to your existing mask frame.
This is a replacement for my cpap mask and it fits well. The price was better than expected. Written by mragbourn, 2017-11-07
I have tried a number of nasal mask and cushion cpap interfaces. My favorite is the Dreamwear system, but the Airfit N20 has been every bit as good in my estimation. The headgear is comfortable, and I love the magnetic clips that allow instant removal when needed. The nasal mask fit comfortably from the first time I put it on. I was able to fit it in about two minutes, and once adjusted it stays in place throughout the night for me with virtually no leaking. After washing, the mask snaps back into place, and fits just as well the next wearing. I've tried a lot of masks, so I guess the learning curve gets easier with experience, but this is the first mask I've had in which there wasn't really any learning curve at all. Also, like the Dreamwear, this mask couldn't be easier to assemble, disassemble, and clean. Great mask. Written by shdeakins, 2017-02-19
