The cushion for the ResMed AirFit F30i full face mask, ResMed United Kingdom catalogue reference 63350. It is the part that seals against the face and the part that wears out, supplied here new and on its own so that a working mask is kept in service rather than bought again.
The F30i cushion is an under the nose design rather than a conventional full face cushion. It seals around the mouth and beneath the nostrils instead of covering the bridge of the nose, which removes the commonest site of pressure marking and leaves the field of view clear. That is what the mask is chosen for, and it is also why the cushion matters more than on other masks: the seal is made on a smaller, more mobile area of the face, so a cushion that has softened or distorted leaks long before it looks worn out.
ResMed make this cushion in four sizes, identified on the part and the packaging by symbol: small, medium, small wide and wide. Those are two separate dimensions rather than one scale. Small and medium describe the height of the cushion, while the wide versions carry the same height with a broader opening for a wider mouth and nose. A wearer who leaks at the corners of the mouth usually needs a wide rather than a larger size, which is the fitting error that sends most cushions back.
It clips to the frame on a tab that snaps into a slot in the cushion, and comes away by gripping the frame connector and lifting one side at a time, so no tools and no re-threading of headgear are involved. The material is silicone and plastic, and it is not made with latex. ResMed call for daily cleaning: a soak in warm water with a mild liquid detergent, a hand wash with a soft bristle brush paying attention to the vent holes, a rinse under running water and air drying out of direct sunlight. Supplied new.
