The AirFit N20 was designed to be so easy to put on and use that you don’t necessarily need specific fitting instructions or “rules.” The secret is in the simple, modular design and magnetic clips, which guide the mask’s headgear to its frame quickly and easily.
Each size mask comes with a standard size headgear that should fit most.
Recommended replacement annually, with cushion being replaced as needed for proper seal. Wipe down once a day with a damp cloth and wash in warm, soapy water once a week with a gentle soap.
