Supporting you
Supporting your patients


Designed to comfortably fit a broader range of patients, AirFit N20 features an entirely new cushion design. To make fitting your existing patients easier, we recommend using our sizing guide – included in each AirFit N20 box and specifically designed to help patients find the right fit. You can also download a copy of it from the ResMed website.

The sizing guide has three cut-outs: small, medium and large. Find the size that accommodates your patient. The modular design of AirFit N20 means each size cushion easily clicks into the same mask frame for easier setup.

Do not overtighten as this may cause discomfort.

Managing leak with your AirFit N20

Leak often occurs when your mask’s seal is compromised by movement, incorrect fitting or improper sizing.

To find a source of leak, run your finger along the edge of your mask’s seal. Once located, adjust your headgear.

Resolve any leak in the upper part of your mask by adjusting your upper straps.

Resolve lower mask leak with your lower straps.

If leak persists, reseal by briefly pulpng your mask away from your face and letting your cushion reinflate.

If leak continues, you may need a different size mask. Try our sizing guide or speak to your healthcare provider about getting a different size mask.
