Sizing & Adjusting the Fit

Use this head-form diagram and sizing chart to determine the Airgami size that fits you best. 

All sales are final. We do not accept returns or exchanges. First-time customers: We recommend that you buy only ONE Airgami in the desired size and harness configuration to test the fit. 

How To Measure

Hold a ruler flush against your skin (not away from your face). Look in a mirror to read the measurements. If you use a tape, be sure to measure approximately straight-line distances, not following the contour of the face.

What To MeasureAirgami Sizing Headform

Nasal bone

Width: Width of the mouth from corner to corner.

Length: Length from the bottom of the nasal bone to the base of your chin. The bottom of the nasal bone is located about 1/3 of the way down from the nose bridge to the tip of the nose.

Choose Your Size

Use both measurements to look up your size in the table below. If your measurements are in the overlap of two sizes, please follow the guidelines below.

  • For regular usage, choose the smaller size that fits both the width and length. For examples, for " width and 4" length, choose S; for 2½" width and 4½" length, choose M. 
  • For singing, choose the larger size that fits both the width and length. For examples, for " width and 4" length, choose M; for 2½" width and 4½" length, choose L.
  • Based on our experience fitting people in person, the best size for most women has been either S or M.
  • Not many people would need XL.

Donning Airgami

Important: Please handle Airgami by the lobes only. These are where the harness attaches to the mask on the left and right sides.

Orient Airgami with the Infinite-a logo up. Hold the lobes to bring the mask to your face and place your chin in first. Place the ear loops around your ears for the ear loop configuration. Place the head straps behind your head and neck for the head strap configuration.

Look in the mirror to make sure that Airgami is sitting symmetrically on your face and isn't twisted or distorted. The first crease below each eye and the diagonal crease on each side of the nose bridge should be flat on the skin.

Do not press Airgami against your face after you don it. There is no nose wire to shape. Pressing the surface of Airgami can deform the folds, which could negatively impact fit and seal.

If deformation happens by accident, use fingers to gently push the folds from the inside of Airgami. In most cases, the deformed folds could snap back into place.

Sizing Micro-adjustment

The harness elastic controls tension on the folded bellows. Tightening the bellows creates a smaller perimeter that comes in contact with your face, thereby fitting a smaller face. Loosening the bellows fits a larger face.

The same harness elastic controls tension on ear loops or head straps. The greater the tension, the tighter the mask presses into your face, creating a tighter seal and vice-versa.

Although "cuffing" is one of the adjustment options, please use cuffing as the last resort. It is best to get a good fit without cuffing, especially on the nose side.
