Note: These videos show a version of AirFit N30i that may differ from the version you use.

Sizing the Frame:

Step 1 - in general, men should select the Standard frame size and women should select the Small frame size. These are general recommendations that can be disregarded if you feel that you have a smaller/larger face than average.

Step 2 - the frame should sit on the top of the head, like a headband. If the frame is too small, it will feel tight and sit too close to your forehead. If the frame is too large, it will feel loose and sit too far back on your head.

Sizing the Cushion:

Step 1 - print the Sizing Template, ensuring it is printed to scale.

Step 2 - place the template below your nose, perpendicular to your face. If you have a narrow nose, start with the blue/red side of the template. If you have a wide nose, start with the black/purple side of the template.

Step 3 - look into a mirror and assess whether your nose falls inside or outside the margins on the template. If you are between two sizes, choose the larger one.

If you don't want to use the sizing template, refer to our sizing guidelines in the table below. Use a straight ruler to measure the width of your nose.
