- To find a leak, run your finger along the edge of your mask seal until you can feel air escaping.
- Leak in the upper part of your mask can be resolved by adjusting the upper straps.
- Leak in the lower part of the mask can be resolved by adjusting the lower straps.
- 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 using our sizing guide or speaking to your ResMed Authorised Dealer about different size masks.
