• 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.
