Every patient’s face is different, but with our new AirFit N20, fitting a broad range of patients can be easy. This compact nasal CPAP mask gives patients a clear line of sight and accommodates their movements thanks to the InfinitySeal™ silicone cushion – made to seal robustly regardless of facial shape or size.
Easy to fit
In a ResMed international study, our new AirFit N20 fit 99.4% of all patients tested. Set patients up right the first time: the silicone cushion adapts to different face shapes and sizes.
Comfortable to use
There’s lightness and softness all around – from the cushion to the frame to the headgear.
Visual freedom
With its streamlined, minimal-contact fit and under-eye frame, the AirFit N20 allows patients to read or watch TV in bed.
Key Features of the ResMed AirFit N20 Nasal Mask
+ Soft and gentle: The plush headgear is specifically designed for extra softness and to help ensure patients settle into therapy quickly and comfortably.
+ Dependable seal: Set patients up with a reliable and effective seal thanks to the InfinitySeal silicone cushion – designed to prevent blow-outs, tolerate misfitting and seal well under variable pressures.
+ Extra movement: A short, flexible tube interconnects the elbow to the machine tube. It’s designed to allow patients to move more easily without encountering tube drag or leakage.
+ Soft frame: Padding has been seamlessly incorporated into the face-side of the frame to ensure comfort at every touchpoint.
+ Visual freedom: Let patients see and do more in bed with an under-the-eye frame that combines all-round stability and less facial contact.
+ Fast fitting time: Taking the mask on and off is convenient and easy, with magnetic clips that guide the headgear to the frame in seconds.
