CPAP & BiPAP masks
CPAP Mask Leaks, Marks & Comfort Fixes
Quick Answer
Most leaks come from a worn cushion, oily skin, or a mask that’s too tight or the wrong size. Wash your face and cushion, refit while lying down with the machine on, and replace cushions on schedule.
Fit it right
- Put the mask on and adjust it while lying in your sleep position with the machine running — fit changes when you lie down.
- Loosen rather than tighten: an overtightened mask folds the cushion and causes more leaks and red marks.
- Use your mask’s fitting guide to confirm the size; weight change or a new cushion can change your size.
Keep it clean
- Wash your face before bed to remove oils and lotions.
- Wipe or wash the cushion daily with mild soap and water and let it air dry.
- Cushions and pillows wear out — a leak that keeps getting worse usually means it’s time for a replacement.
Dry mouth or nose
- Waking with a dry mouth can mean mouth breathing with a nasal mask — a full-face mask or chin strap may help; ask your prescriber.
- Turn up humidification or use heated tubing if your machine supports it.
