Particulate Respiratory Protection

Particulate respirators worn over the nose and mouth protect the wearer from inhaling hazardous particulate matter such as dusts and airborne biohazards. The level of protection depends upon filtration effectiveness and the tightness of the seal around the edges of the mask when it is worn. The National Institute for Occupational Safety and Health (NIOSH) tests and certifies particulate air purifying respirator products that exceed the minimum 95% level of filtration. Respirators required in the workplace are regulated by the Occupational Safety and Health Administration (OSHA).
