Here is information and suggestions for the COVID-19 test and the entire test location.

 
Kn95 is a Chinese standard respirator, which comes from the Chinese national standard GB 2626-2006 self suction filter type particle respirator for respiratory protective equipment. According to our national standard, respirators can be divided into kn and KP categories according to their functions. Kn category is suitable for filtering non oil particles and KP category is suitable for filtering oil particles. The following figure is the percentage of filtration efficiency, kn95 specifies that the filtration efficiency of non oil particles above 0.075 μ m is greater than 95% . Issued to the whole society on December 31, 2019 with the announcement of National Standard No. 17, 2019 of the people's Republic of China, and will be officially implemented on July 1, 2020.
It has clear regulations on the technical requirements of appearance inspection, leakage, respiratory resistance, exhalation valve, dead cavity, vision, headband, connecting and connecting parts, lenses, air tightness, flammability, cleaning and disinfection, information that manufacturers should provide, packaging and so on. At present, the text of the new standard has been published and made free to the whole society as a compulsory standard. Seven terms such as "aerodynamic particle size" are added to the new standard, and some technical requirements and detection methods are modified.
N95 respirator is one of nine kinds of particle respirators certified by NIOSH (National Institute for occupational safety and health). N95 is not a specific product name. As long as the product meets the N95 standard and passes the NIOSH review, it can be called N95 respirator, and the filtration efficiency of particles with aerodynamic diameter of 0.075 μ m ± 0.020 μ M can reach more than 95%.
