Why is My CPAP Mask Leaking? Causes and Prevention Tips

13/10/2021

Sleeping with Obstructive Sleep Apnea (OSA) is like scuba diving with a snorkel mask. Every time you take a breath, you resurface with a choke and a splutter.

Lack of proper equipment keeps you from diving deep into the dreamworld below the surface.

If you have a CPAP machine, you probably feel like the diver who upgraded the snorkel mask for a dive regulator and an oxygen tank. You can finally breathe comfortably and consistently throughout the night.

But what if your new "diving gear" – your CPAP mask – starts leaking air?

What causes a CPAP mask to leak air?

A CPAP machine works by increasing and maintaining the air pressure in your throat to prevent the walls of your throat from collapsing during sleep. It's among the oldest but most effective treatments for sleep apnea, but when a CPAP mask is leaking air, it can compromise your therapy and leave you feeling congested and tired when you wake up.

These machines consist of several parts: tubes, filters, hoses, straps, connectors, headgear, filters, and--of greatest interest to us right now--masks.

CPAP masks come in three basic varieties:

1. The full face mask

It covers the nose and mouth, sealing both airways. If you breathe through your mouth, need higher pressure settings, or sleep on your back, your doctor may prescribe this type of mask. Due to its larger surface area, the full face mask is more likely to leak air if not fitted properly.

2. The nasal pillow

This is usually prescribed to people who have heavy facial hair, toss and turn during their sleep, or consistently breathe through their noses. Nasal pillows seal just the nostrils, making them comfortable, but they may start leaking air after a few hours if they are dislodged during sleep.

3. The nasal mask

This type covers the nose from the lip to the upper bridge and may be the most versatile (and popular) of the three choices. It's not as bulky as the full face mask but not as lightweight as the nasal pillow. Still, moving in your sleep can cause it to this type of CPAP mask to leak air.

Any CPAP mask can leak air if it's the wrong size, doesn't match your facial structure, has the pressure set too high, gets worn out, or is dislodged by you moving in your sleep.

A leaking CPAP mask can leave you searching for the snooze button like you did in the days before you got your CPAP.

Four steps to prevent your CPAP mask leaks

If your CPAP mask is leaking air, don't rip it off and suffer from apnea.

  1. Check the mask’s fit. If it's too tight or too loose, adjust the straps or wait until you're in your sleeping position before putting it on.

  1. Don't forget to wipe out the mask daily and submerge it in soapy water weekly. Keeping your mask clean will help prevent leaks.

  2. While you're washing the mask, check its seal. If it looks old, get a new one.

  3. Finally, talk to your doctor about prescribing you a different style of mask or machine.

There's no reason to stop diving into dreamland just because of a leaky CPAP mask.

FAQs about CPAP Mask Leaks

Why is my CPAP mask leaking air?

CPAP masks can leak air if they are not properly fitted, if the pressure setting on your machine is too high, or if the mask parts (like the seal or headgear) are worn out. Adjusting the fit, cleaning the mask, or replacing worn components can help resolve the issue.

How can I stop my CPAP mask from leaking?

To prevent leaks, ensure that your mask fits snugly but comfortably. Adjust the straps while in your usual sleeping position. Regularly clean your mask and replace worn-out seals or other parts. If leaks persist, you may need a different mask style or size.

Why does my CPAP mask leak after a few hours of use?

CPAP mask leaks after a few hours can happen due to changes in your sleeping position or if the mask becomes dislodged. It could also be due to a loose fit or worn-out mask components. Adjust the mask or consider a different type of mask that fits better with your sleep habits.

What should I do if my CPAP mask is leaking air?

If your CPAP mask is leaking air, first check the fit and adjust the straps. Ensure the mask and seal are clean, and look for any signs of wear. If the mask continues to leak, consult with your doctor to discuss alternative options or pressure adjustments.

Can a CPAP mask leak cause poor sleep?

Yes, a leaky CPAP mask can cause disruptions in your sleep by reducing the effectiveness of your sleep apnea therapy. You may wake up feeling congested or tired. Resolving the leak is essential to ensuring a restful night’s sleep and effective sleep apnea treatment.

What type of CPAP mask is less likely to leak?

The best CPAP mask to prevent leaks depends on your individual needs. Full face masks are more prone to leaks due to their larger surface area, while nasal pillows or nasal masks might be better for active sleepers. Finding the right fit and mask type is key to preventing leaks.

Can facial hair cause my CPAP mask to leak?

Yes, facial hair can prevent CPAP masks from sealing properly, leading to air leaks. Nasal pillows are often recommended for people with facial hair, as they only seal around the nostrils, making them less affected by facial hair.
