FDA standard for n95?

N95 Respirator is a personal protective equipment that prevents the wearer from inhaling aerosols (dust, smoke, mist) and vapors or gases (disinfectants, anesthetic gases) that are harmful to health. It is unusable in pharmacies and protects the wearer from infectious agents in the air, that is, from viruses such as coronavirus, SARS, H1N1 and others.


Respirators are divided into two categories: insulated and filtered. The filter respirator consists of a mask and a filtering device. Sometimes the filter element is integrated into the mask. Depending on the type of filter, the mask will only work on particles, only on certain gases and vapors, or on particles, gases and vapors.


Filtered gas masks can sometimes be equipped with exhalation valves to improve user comfort.


In the United States, respirators must meet NIOSH (National Institute of Occupational Safety and Health) standards. Within this standard, respirators are divided into several categories based on their oil resistance:


N level: no oil resistance. There are differences between N95, N99 and N100. The number after the letter indicates the percentage of filtration of suspended particles.

Grade R: Oil-resistant mask for up to eight hours. Here again, a distinction is made between R95, R99 and R100.

P-Class: Fully oil-resistant mask. There are also P95, P99 and P100.

Among them, N95 is a mask that needs to pass the certification for export to the United States.
