Adjusting for Leaks
- If you experience leaks, try these steps:
1. With your CPAP or bi-level machine on and at your prescription pressure,
pinch the portion of the mask directly over your nose, pull the mask
slightly away from your face, towards your feet, and gently release.
2. If you experience leaks from the sides of the mask, adjust the Neck
Straps by unhooking the tab from the strap and pulling the straps out
to tighten the mask, then re-attach the tab to the strap.
3. If you experience leaks into your eyes, adjust the Head Strap.
4. At times it is possible to stop leaks and get a better fit by loosening the
mask just a bit, then repeating Step 1.
5. Leaks can also occur if the headgear straps are too tight or too loose.
With practice you should find the snug but comfortable fit that works for you.

mild nonabrasive soap in warm water every other day. Never use hot water.
Repeat washing until visibly clean. Hand wash the headgear weekly.
