Strengths
- ResMed states that it fits 99% of the people tested.
- Compatible with the ResMed AirMini according to ResMed's compatibility list.
- Same frame as the AirTouch N20, so you can switch to the foam cushion without changing masks.
Watch out for
- Magnets in the frame and headgear clips: contraindicated if you or your bed partner has certain implants, and a 150 mm safety distance applies.
- The cushion covers the bridge of the nose.
- Nasal mask: if you breathe through your mouth, air escapes.
Best for
- Nose breathers who keep their mouth closed
- Side sleepers (a profile highlighted by ResMed)
- Glasses wearers who read or watch TV in bed (a profile highlighted by ResMed)

Manufacturer warning: magnets
Magnets sit in the frame and the lower headgear clips (field strength up to 400 mT) and may detach during sleep. Contraindicated if you, or anyone in close physical contact while the mask is in use (such as a bed partner), has an active implant that interacts with magnets (pacemaker, implantable cardioverter defibrillator, neurostimulator, cerebrospinal fluid shunt, insulin or infusion pump) or a metallic implant or object containing ferromagnetic material (aneurysm clip, embolic coils, stents, valves, electrodes, hearing or balance implant with magnets, ocular implant, metal splinter in the eye). Keep the magnets at least 150 mm (6 inches) away from any implant or medical device that could be affected. ResMed's Field Safety Notice of 20 November 2023 raised this distance from 50 mm to 150 mm and broadened the contraindications; ResMed updated the labeling rather than withdrawing the mask, and the FDA classified the action as a Class I recall in the United States.
