Why Is My CPAP Mask Leaking? Common Causes & How to Fix It
Posted On: October 27, 2025 by CarePro Health Services in: CPAP Respiratory
If you’ve ever woken up to the hiss of escaping air or felt a cool breeze on your face in the middle of the night, you’re not the only one. CPAP mask leaks are one of the most common frustrations for people using CPAP machines to treat sleep apnea.
At CarePro Home Medical and Kelly’s Home Medical, we know how important it is for your CPAP equipment to work the way it should. A leaky mask can keep you up at night, lower your therapy’s effectiveness, and make it harder to stay consistent with treatment.
Let’s go over the most common causes of CPAP mask leaks and what you can do to fix them.
1. Poor Mask Fit
A mask that doesn’t fit right is the top reason for air leaks. If it’s too loose, too tight, or not shaped properly for your face, the seal can break and cause air to escape.
How to fix it:
- Adjust your headgear straps so the mask feels snug but not tight.
- Check that the mask cushion sits evenly on your face.
- If it still leaks, you might need a different style or size.
CarePro and Kelly’s Home Medical offer a wide variety of mask options, and our respiratory care team can help you find the style that fits your facial shape and sleep position best.

2. Worn-Out Mask Parts
Like most medical equipment, CPAP masks wear down over time. The silicone or gel cushions can lose their softness, stretch, or develop small cracks that prevent a tight seal. This is especially common if the mask isn’t cleaned or maintained regularly.
How to fix it:
- Look for signs of wear such as discoloration, stiffness, or cracks.
- Replace your mask cushions regularly, usually every few months.
- Keep your mask clean to prevent buildup that can weaken the seal.
Replacing parts on time helps keep your therapy comfortable and effective.

3. Incorrect Pressure Settings
If your CPAP machine is set to deliver air at a higher pressure than you need, it can cause air to push out around the mask edges.
How to fix it:
Never change your pressure settings yourself. Instead, schedule a check with your sleep specialist or a CarePro or Kelly’s respiratory therapist. During a CPAP appointment, we’ll inspect your machine, verify your pressure settings, and make sure everything is working correctly.

4. Sleeping Position
Your sleeping position can affect how well your mask seals. Side and stomach sleepers often notice leaks when the mask shifts against the pillow.
How to fix it:
- Try using a CPAP-friendly pillow, which has cutouts to reduce pressure on your mask.
- Experiment with different mask types, some are designed to stay in place better for active sleepers.
It might be time for a new CPAP mask. Schedule an appointment with CarePro and Kelly’s team – you can ask questions about your mask, order new supplies, and we’ll check your pressure settings and tubing.
5. Facial Hair or Skin Oils
Even small details like facial hair or natural skin oils can break the seal of your mask.
How to fix it:
- Wash your face before bed to remove oils or lotions.
- If you have a beard or mustache, try a nasal pillow mask, which sits under your nose and tends to work better with facial hair.

6. Mask Type Mismatch
Not every mask type works for every person. For example, a nasal mask might not seal well if you tend to breathe through your mouth, while a full-face mask can feel bulky if you sleep on your side.
How to fix it:
If you’ve tried adjusting your mask and still have leaks, it might be time to switch to a new style. There are nasal, nasal pillow, and full-face options available, and the right one can make all the difference for your comfort and therapy success.
