If you’ve noticed air escaping from your CPAP mask or are waking up feeling tired or uncomfortable, you might be dealing with a mask leak. Don’t worry — it’s a common issue, and there are easy ways to fix it.
A leaking mask means you’re not getting the right air pressure — and that can make your therapy less effective. In fact, mask leaks are one of the top reasons people give up on CPAP. But with a few simple checks, you can keep your therapy on track and wake up feeling refreshed.
Watch for these signs:
Hissing sounds while your CPAP is running
Dry mouth or nose in the morning
Feeling air escape from around your mask
Less pressure than usual
Water running out quickly in your humidifier
Your mask might be too big, too small, or just not the right shape for your face.
✅ Solution: Try adjusting the straps or talk to your provider about trying a different style or size.
Over time, the mask cushion can wear out and stop sealing properly.
✅ Solution: Replace the mask or parts like cushions or headgear regularly.
Face oils and dust can break the seal between the mask and your skin.
✅ Solution: Clean your mask daily using the manufacturer’s guidelines.
Sleeping on your side or stomach can shift your mask and cause leaks.
✅ Solution: Try sleeping on your back or use a CPAP-friendly pillow.
If your machine is set to a high pressure, it might put extra force on the mask seal.
✅ Solution: Choose a mask designed for high-pressure therapy.
Air can escape from your mouth while you sleep.
✅ Solution: Use a chin strap or consider switching to a full-face mask.

A CPAP mask leak can interrupt your sleep and reduce the benefits of therapy — but it’s usually easy to fix. Keep your gear clean, make sure it fits right, and don’t ignore the signs. A quiet, comfortable night’s sleep is possible!
