  1. 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.
  2. 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.


  1. Unclip EasyClick Magnets.
  2. With your patient holding the mask towards their face, slide the headgear over the back of their head.
  3. Reclip EasyClick Magnets.
  4. Adjust the tabs on the upper headgear straps.
  5. Adjust the tabs on the lower headgear straps. The upper headgear straps provide most of the adjustment. The lower headgear straps can be used to gently tighten a patient’s mask. Do not overtighten as this may cause discomfort. If your patient experiences leaks, or for additional information on mask maintenance and care, you can also visit the Supporting your patients section for more videos.

Managing leak with your AirFit N20

  1. Leak often occurs when your mask’s seal is compromised by movement, incorrect fitting or improper sizing.
  2. To find a source of leak, run your finger along the edge of your mask’s seal. Once located, adjust your headgear.
  3. Resolve any leak in the upper part of your mask by adjusting your upper straps.
  4. Resolve lower mask leak with your lower straps.
  5. If leak persists, reseal by briefly pulling your mask away from your face and letting your cushion reinflate.
  6. 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.
