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 to locate where air is escaping.
Leak in the upper part of your mask can be resolved by adjusting your upper straps.
Leak in the lower part of the mask can be resolved with your lower straps.
However, do not overtighten as this may cause discomfort.
If leak persists, with your device still switched on, reseal by briefly pulling your mask away from your face and letting your cushion reinflate.
If these steps do not resolve the issue, you may need a different size mask. Try using our sizing guide or speak to your CPAP provider using a different sized mask.
