As we all know, aerosol transmission is an important transmission route of the novel coronavirus. Therefore, when choosing a mask, people should pay attention not only to the filtration efficiency of BFE, but also to the filtration performance of PFE, which directly determines the protective performance of the whole mask.
General international standards for masks
1. American Standard
NIOSH 42 -84 quot; NIOSH Guide to the Selection and Use of Masks quot;Particulate Respiratorsquot; is issued by NIOSH (National Institute for Occupational Safety and Health) and is a technical specification of the American Federal Regulations CFR.

International standard for medical masks
The main function of medical masks is to filter particles in the air and block droplets, blood and body fluids, secretion droplets, etc. The most important technical indicators for the protective performance of medical masks are the filtration efficiency of particles and bacteria, and the resistance to blood penetration.
1. European standard
EN 14683-2019 quot;Medical masks - requirements and test methodsquot; This standard is a European standard, formulated and publishedby the European Committee for Standardization CEN, and implemented in 34 EU c countries.
