Choosing a CPAP mask is one of the most important steps in making sleep therapy feel comfortable and sustainable. The best style is not the same for everyone: your usual breathing pattern, sleep position, pressure needs, and facial comfort all matter.
Start with your breathing and sleep habits
- Full face masks cover the nose and mouth. They are often a practical option for people who breathe through their mouth during sleep, wake with a dry mouth, or have frequent nasal congestion.
- Nasal masks cover the nose only. They can offer a familiar, balanced fit for people who usually breathe through the nose and want more freedom around the mouth.
- Nasal pillow masks rest at the nostrils and use minimal facial coverage. They may suit users who prefer a lighter feel, read in bed, or sleep on their side—provided the seal remains comfortable.
Full face masks: coverage for nose-and-mouth breathing
A full face mask may be worth considering if you often breathe through your mouth, experience congestion, or need a secure seal at higher therapy pressures. Correct cushion size and headgear tension are essential: tightening a mask too much can create discomfort and may even worsen leaks.

Nasal masks: a balanced, everyday option
Nasal masks are designed for people who generally breathe through the nose. Their smaller profile can feel less enclosing than a full face mask while still providing a stable seal. If you regularly open your mouth while sleeping, discuss solutions with your sleep-care professional before selecting this style.

Nasal pillows: minimal contact around the face
Nasal pillow masks use soft inserts at the nostrils rather than a cushion over the nose. Many users appreciate the open field of view and low-contact design. A proper pillow size is important: it should seal gently without pinching or creating persistent soreness.
How to improve mask fit
- Measure and follow the manufacturer’s fitting guide rather than choosing by guesswork.
- Fit the mask while lying in your normal sleeping position, with therapy running if possible.
- Begin with the straps comfortably snug—not overtightened—and make small adjustments.
- Clean the cushion regularly. Facial oils and worn parts can make leaks more likely.
- Replace cushions, headgear, and other consumable parts according to the product guidance and your clinician’s recommendations.
The takeaway
There is no single “best” CPAP mask. A full face style may help with mouth breathing; a nasal mask can be a comfortable everyday choice for nasal breathers; and nasal pillows may suit those seeking minimal facial contact. Prioritize a secure but gentle seal, comfort through the night, and a style that supports consistent therapy use.
