Face Masks A face mask is a product that covers the wearer’s nose and mouth. Barrier face coverings may be made from a variety of materials that are not flammable. By definition, a barrier face covering should meet the particulate filtration efficiency, airflow resistance, and leakage assessment recommendations as described in ASTM F3502-21. Surgical Masks A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment.

Surgical masks are regulated under 21 CFR 878. Surgical masks are not to be shared and may be labeled as surgical, isolation, dental, or medical procedure masks.
