Respirator cartridge (3M 6009) for protection against mercury vapor and chlorine. This cartridge has an indicator that progressively changes color (from yellow to black, 1-2-3-4) when it is exposed to mercury vapor.
During the COVID-19 pandemic, the mask and respirator market rapidly grew, along with counterfeit respirators. [1] NIOSH, on behalf of the Department of Health and Human Services, filed a trademark application on June 17, 2020, for various 42 CFR 84 trademarks, including the N95, allowing NIOSH to enforce rules on counterfeit masks outside of rules defined in 42 CFR 84.
According to 3M, respirators made according to the following standards are equivalent to US N95 or European FFP2 respirators "for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses)": [40] Chinese KN95 (GB2626-2006): similar to US.
Air-purifying respirators range from relatively inexpensive, single-use, disposable face masks, known as filtering facepiece respirators, reusable models with replaceable cartridges called elastomeric respirators, to powered air-purifying respirators (PAPR), which use a pump or fan to constantly move air through a filter and supply purified air ...
The N95 respirator mask was developed by 3M and approved in 1972. [112] Due to its ability to filter viral particulates, its use was recommended during the COVID-19 pandemic but supply soon became short. [ 112 ]
An N95 respirator is a disposable filtering facepiece respirator or reusable elastomeric respirator filter that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 standard of air filtration, filtering at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers under 42 CFR 84, effective July 10, 1995.
