Managing leak with your AirFit N20 Classic

  1. Leak often occurs when your mask’s seal is compromised by movement, incorrect fitting or improper sizing.
  2. Step 1 - To find a source of leak, run your finger along the edge of your mask seal to locate where air is escaping.
  3. Step 2 - Leak in the upper part of your mask can be resolved by adjusting your upper straps.
  4. Step 3 - Leak in the lower part of the mask can be resolved with your lower straps.
  5. Step 4 - If leak persists, reseal by briefly pulling your mask away from your face and letting your cushion reinflate.
  6. If these steps do not resolve the leak, you may need a different size mask. Try using our sizing guide or speaking to your healthcare provider about different size masks.
