The components should be washed using warm water and a mild detergent and allowed to dry out of direct sunlight as follows:
- Daily: Cushion, Elbow, Short Tube
- Weekly: Headgear (with clips), Frame
When washing the headgear and frame, squeeze them to ensure all soapy water has been rinsed out, and also squeeze after rinsing to eliminate excess water before drying.
For choosing the correct size, please use the sizing guide found towards the top right of this page. Measure the ruler on the printed sizing guide to ensure it printed properly and to scale. The sizing guide uses the width of the nose as its determining factor.
The AirFit N20 has three interchangeable cushion sizes - small, medium, and large. Each size cushions easily clicks into the same mask frame so users can swap between them with ease for more flexibility. The size can be found on the bottom of the cushion, marked either S, M, or L.
