When we review CPAP machines and accessories, we use our team’s decades of medical and sleep health experience. The best CPAP masks for mouth breathers are models that we’ve vetted for compatibility, effectiveness, and comfort. We use real verified reviews, peer-reviewed data, and health professionals’ recommendations to determine whether or not to promote a model to our readers. For this review, we relied specifically on user data from people who breathe through their mouths, considering what they thought of a model during practical use.
If you breathe through your mouth while sleeping, you’ll probably find that a full-face CPAP mask works best. With a nasal mask, the air delivered by the CPAP machine can escape through your mouth instead of working to keep your airway open. A full-face mask is typically better at preventing air leaks when mouth breathing.
Experts recommend giving nasal masks a try, as research shows they’re generally more effective and many people naturally transition to nose breathing after starting CPAP therapy.
A chin strap can reduce air leaks from mouth breathing while using a nasal mask. If nasal congestion makes it difficult to breathe through your nose, ask your doctor about nasal sprays, nasal strips and dilators, antihistamines, or a humidifier.
| Mask Type | Description | Benefits | Drawbacks |
| Full-Face Mask | A full-face mask covers the mouth and nose. This design minimizes air leaks from the mouth and ensures that the CPAP airflow reaches the airway. |
|
|
| Nasal Mask | Most nasal masks run from the bridge of the nose to just above the mouth, though some nasal cradle models rest beneath the nose and seal against the nostrils. |
|
|
| Nasal Pillow Mask | Nasal pillow masks are more minimalist than nasal masks, with soft inserts that seal just inside the nostrils. |

We often recommend full-face masks to people who breathe through their mouths because they’re less likely to leak. Some people find their large size uncomfortable, but memory foam cushions and mask liners can help.
When choosing a CPAP mask for mouth breathing, look for one that fits comfortably and is compatible with your CPAP machine. You should also consider personal factors like sleeping position, budget, and whether you feel comfortable wearing a chin strap.
A comfortable, well-fitting CPAP mask reduces unintentional air leaks and helps ensure you’re getting the most effective CPAP treatment. Each model has a slightly different design, so finding the right fit may involve some trial and error.
A CPAP chin strap can help keep your mouth closed and prevent unwanted mouth leaks. You may need to switch to a full-face mask if you have significant nasal congestion, if air leaks continue after adding a chin strap, or if you find the chin strap uncomfortable.
Full-face masks work best for mouth breathing. However, these masks may cause unintentional mask leak for side and stomach sleepers. Some companies offer lower-profile full-face masks that are less restrictive. If you can’t sleep on your back, another alternative is to buy a nasal mask and add a chin strap.
CPAP mask manufacturers generally provide information about device compatibility. Depending on the manufacturer, you may need to purchase a mask from the same company that makes your CPAP machine. Check the specifications to confirm the mask works with your required pressure settings.
Masks are a separate purchase on top of the cost of a CPAP machine, although they’re often covered by insurance. Full-face CPAP masks generally cost between $60 and $200, nasal masks between $50 and $175, and nasal pillow masks between $70 and $120. Replacement mask cushions typically run between $20 and $60.
Your sleeping position factors into what kind of mask you should get. Full-face masks can shift if you sleep on your side, so if that’s your preferred sleeping position and you breathe through your mouth, you may want to think about a nasal pillow and chin strap combination.
Buying a CPAP mask involves a few practical considerations beyond choosing the right design. Depending on where you shop and how you plan to pay, you may need a prescription, insurance approval, or specific documentation before you can make a purchase.
Although CPAP masks are purchased separately from the CPAP machine, you need a prescription to purchase the mask as well. Retailers usually ask for a copy of the prescription before selling the mask. Mask replacement parts, including cushions and headgear, are available without a prescription.
If you complete a home sleep test through Sleep Doctor, our team can help determine whether you need a prescription and guide you through next steps.
As part of CPAP therapy, the cost of purchasing a CPAP mask is at least partially covered by Medicare, Medicaid, and many private insurance plans. Note that many insurers have specific CPAP compliance requirements. For example, to remain eligible for Medicare coverage, you must demonstrate that the CPAP machine is helping you and that you use the device at least four hours per night on 70% of nights.
CPAP masks are sold online and in physical stores. You may also be able to purchase a mask through your doctor or sleep specialist.
Sleep Doctor offers a curated selection of CPAP masks from leading manufacturers, with detailed product information to help you choose an option that works for mouth breathing. Shopping online through Sleep Doctor allows you to compare mask styles, check compatibility, and have your mask delivered directly to your home.
While it’s possible to use a nasal CPAP mask if you breathe through your mouth, most people find full-face models to be the best CPAP mask type for mouth breathing. Nasal masks may be more susceptible to air leaks in this situation, particularly if you have a blocked or stuffy nose.
