Who Tested Our Masks?

Our lab tested masks use standards set by the American Society for Testing and Materials (ASTM) and the American Association of Textile Chemists and Colorists (AATCC). We leveraged best-in-class industry leading laboratories to conduct the tests, including TÜV Rheinland and SGS.

The tests include efficacy ratings of the various finishes applied to layers of our masks, as well as Particle Filtration, Bacteria Filtration, and Virus Filtration Efficiencies.
