Any tips on managing mask leak with the AirFit N20 Classic nasal mask?

AirFit N20 Leak

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


    1. To find a leak, run your finger along the edge of your mask seal until you can feel air escaping.
    2. Leak in the upper part of your mask can be resolved by adjusting the upper straps.
    3. Leak in the lower part of the mask can be resolved by adjusting the lower straps.
    4. If leak persists, reseal by briefly pulling your mask away from your face and letting your cushion re inflate.

    If these steps do not resolve the leak, you may need a different size cushion. Try speaking to your ResMed Authorised Dealer about different size masks.
