Full-face masks, also called oronasal masks

Full face masks cover the nose and mouth to supply air pressure. These masks might be a good choice if:

• You have nasal blockage or congestion that makes it hard to breathe through your nose.
• You breathe through your mouth at night despite a month of trying a nasal mask or nasal pillow. A nasal mask or nasal pillow are typically combined with a heated humidity feature, a chin strap or both to keep your mouth closed.
