OGDEN, Utah, June 2, 2021 /PRNewswire/ -- Makana Masks, the American manufacturer of innovative reusable safety masks, has received certification from Nelson Labs as a Level 1 Barrier Face Covering. Makana is the first and only elastomer reusable half-face mask to receive this important certification.
Specifically, Makana Masks have been found to comply with ASTM F3502, "Standard Specification for Barrier Face Coverings." To achieve this standard, masks undergo a sodium chloride aerosol challenge (NaCl) to evaluate filtration efficiency, as well as an airflow resistance test to measure breathability. Having met Level 1 standards, Makana Masks are now advancing to Level 2 testing.
