N95 masks were originally used in industrial industries such as mining, construction and paint, but later the mask is to prevent the spread of drug-resistant tuberculosis, and began to be used in the medical industry. In the 1990s, drug-resistant tuberculosis was at rise. In order to prevent airborne transmission, the N95 standard and N95 masks were widely popularized. Later, the World Health Organization recommended the use of N95 masks to prevent airborne diseases.
