FAQ: What materials are used to make a USA mask?
USA Masks are made of non-woven fabric, at 20 to 25 grams per square meter in density. We use three layers of material, a melt-blown polymer (usually polycarbonate, polyethylene, polypropylene, polystyrene, or polyester). Masks that are used for dust protection and non-surgical masks can be made of cloth.
- The outer layer repels water, blood, and other body fluids
- The middle layer filters certain pathogens
- The inner layer absorbs moisture and sweat from exhaled air
