The AirFit N20 features the InfinitySeal cushion along with a soft and flexible frame that includes integrated padding.
The N20 nasal mask system by ResMed is by far ResMed™s most comfortable and advanced nasal mask to date.
Much time has been invested in improving all aspects from the previous release of the N10 and whilst the design of this mask looks similar to one of its competitor's masks, it is much stronger and durable. 

Key features of this mask is the technology that has gone into making sections on the bridge of the nose softer and more pliable. This means the mask can be looser on the face and maintain an excellent seal.

The N20 mask also has improved headgear and uses magnets to clip the mask on and off. The magnet technology is revolutionary for ease of securing the mask and undoing it especially for people that have arthritis in their fingers. Unlike the N10 beforehand, this mask's magnets are set back and won't leave a dent in your cheek. The mask is also much more comfortable to wear than the N10 in our opinion.

The N20 mask comes in small medium and large sizes with the standard headgear on the medium and large and small headgear on the small mask.
