NIOSH is recommending a new standard in face masks for workplaces, called
- Workplace Performance and
- Workplace Performance Plus masks
Manufacturing masks that comply with the new NIOSH criteria can help protect people in the workplace from SARS-CoV-2, the virus that causes COVID-19. These masks CANNOT be used as a replacement for respiratory protection when it is needed. The new mask criteria and ASTM Specification for Barrier Face Coverings, F3502-21(ASTM Standard) determine an expected level of source control performance for workers when wearing the mask according to the manufacturer’s instructions.
