"N95" is a standard set by the Occupational Safety and Health Institute (NIOSH) of the United States CDC and is not a specific product name. As long as it meets the N95 standard and passes the NIOSH review, the product can be called "N95 mask".

Among the nine standards formulated by NIOSH, N95 is the minimum standard for infection protection, which is cheap and easy to be adopted by medical institutions. N95 masks are used for occupational respiratory protection, including certain microbial particles (such as viruses, bacteria, molds, anthracnose, tuberculosis, etc.).

The biggest feature of the N95 mask is that it can prevent droplet infection caused by a patient's body fluid or blood splash. The size of the droplets is 1 to 5 microns in diameter. The U.S. Occupational Safety and Health Administration (OSHA) requires medical institutions that medical workers exposed to tuberculosis bacteria must wear masks higher than N95.

N95 masks are tested with 0.3 micron sodium chloride particles. The barrier rate must be more than 95%. When the wearer's face is tightly tested, make sure that the air can pass in and out through the mask when the face is close to the edge of the face. Only those who meet this test will be issued the N95 certification number. In general, protective masks that have passed the domestic existing standards certification have not yet reached the N95 level standard.
