Please see below for expert tips on choosing your cushion size and keeping your equipment in good condition.

Cushion sizing:

  • 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 purple side of the template.

              Step 3 - look into a mirror and assess whether your nose falls inside or outside the marginson the template. If you are between two sizes, choose the larger size.Step 4 - if your nose is size S (red) or M (blue), select the appropriate cushion from your starter pack. If your nose is SW (purple) then you will need to order an SW cushion as a spare part.
