Which one for you?
Rather the AirFit N20 if:
- 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)
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.
Rather the AirFit N30i if:
- Side or stomach sleepers
- A nasal bridge prone to marks
- Glasses wearers who read or watch TV in bed
Watch out for
- Not compatible with the ResMed AirMini.
- Nasal mask: if you breathe through your mouth, air escapes.
- Select the Pillows mask setting on ResMed devices; ResMed notes SmartStop may not work with some devices.
