CPAP masks
The mask is where most CPAP trouble starts: leaks, marks, dry mouth and noise. Start with the type that suits how you breathe and sleep, then size it properly. Masks are prescription items in the US, so your supplier or retailer will ask for your prescription.
Take the mask finderNasal mask
A nasal mask covers your nose only, either with a triangular cushion that sits over the bridge of the nose or with a cradle cushion that sits under the nose. It is the mask type an American Thoracic Society workshop recommends as the first option for most people starting CPAP.
Nasal pillows mask
A nasal pillows mask uses two small soft inserts that rest at the entrance of your nostrils. It is the smallest, lightest kind of CPAP mask and touches very little of your face.
Full face mask
A traditional full face (oronasal) mask covers your nose and mouth with one cushion that seals over the bridge of the nose, along the cheeks and under the lower lip. It lets you breathe through either your nose or your mouth.
Under the nose full face mask (hybrid, minimal contact)
An under the nose full face mask covers your mouth and seals under your nose instead of over the bridge. Manufacturers call these minimal contact or oral nasal masks; examples include the ResMed AirFit F30, F30i and X30i and the Philips DreamWear Full Face.
Oral mask
An oral mask delivers air only through the mouth, using a mouthpiece that sits between the lips and teeth with an outer flap that seals over the lips. It is rarely used today; the best known example, the Fisher and Paykel Oracle 452, has been discontinued.
Total face mask
A total face mask seals around the outer edge of your whole face, covering the eyes, nose and mouth. The Philips Respironics FitLife is the best known example. It is used mostly when other masks cannot seal or cause sores.
