Equipment catalog
ResMed AirFit N30i
Covers the nose (or seals just under it, depending on the model) and leaves the mouth free. It sits between pillows and full face masks in contact surface.
Catalog features
- Top-of-head tube routing — more freedom of movement when turning on the pillow.
- Minimal-contact design: less resting surface on the face.
When this type tends to fit
Meant for people who breathe through the nose during sleep. Models with top-of-head tube routing give more freedom for side sleeping.
This is ergonomic orientation by mask type, not a clinical recommendation: the fit for your face and your therapy is confirmed by your provider or sleep unit.
