A CPAP mask is part of the therapy system, not just an accessory. Nasal masks cover the nose; full-face masks generally cover the nose and mouth or use an under-the-nose full-face design. The right interface depends on prescribed therapy, breathing route, leak, facial fit and comfort.
When nasal masks may suit
Nasal interfaces are often lighter and can provide a smaller facial footprint. Mouth leak, nasal obstruction or inability to maintain nasal breathing can make them harder to use for some people.
When full-face masks may suit
A full-face interface can accommodate mouth breathing, but it has a larger sealing surface and fit still matters. Do not change mask type solely to solve persistent leak without checking size, headgear and therapy setup.
