A product is only as good as the materials it is made from; and this is especially true vis-à-vis face coverings. Researchers and chemical safety experts note that the permeability of various materials can vary widely and in unpredictable ways, making it difficult to determine definitively which material is best for a face covering. The type of fabric used, the tightness of the weave, and their exposure to moistening from the wearer’s breath are all factors that impact performance and breathability in unpredictable ways. While we did in fact conduct an exhaustive review of the subject, we defer to the experts in this area.
For eighty years, the world-renown Argonne National Laboratory* has answered the biggest questions facing humanity by redefine the possible. Recently, it refocused its unparalleled scientific facilities and talent to fight against COVID-19. To that end, with University of Chicago* researchers, it conducted an extensive study of the filtration efficiencies of common face covering fabrics. Published in the American Chemical Society’s ACS Nano (April, 2020) journal, its main exhibit is below. It is noteworthy to mention that this study has been referenced by the CDC and in the community face covering specifications issued by several international bodies. Stanford Medicine* researchers conducted similar studies on face coverings .and electrostatic charges.
