Bellus3D Mask Fitter

Bellus3D's Face Mask Fitter is a plastic frame that helps to improve the seal with surgical masks or similar face masks. It is made using a Bellus3D face scan (created with the Bellus3D FaceApp) and a 3D printer to precisely fit a person's facial geometry.


The mask fitter has undergone testing in a medical setting and has been approved by the U.S. Department of Health and Human Services  —  National Institutes of Health.

Bellus3D Face Mask Fitter

The standard mask is what is pictured; it goes around your nose and chin. There is a new premium mask that has material that comes across the lip area. There is a clamp that is meant to grab the mask material so the mask doesn't go in your mouth when you breathe.
