From the perspective of epidemic prevention, stand from the practical perspective of "filtering viruses". Many people will also take it for granted that the virus is so small, that if the BFE99 mask has the insufficient blocking ability to 0.1-micron particles, it is useless.
This assumption is based on the imagination that "a virus can infect people", but this is not the case in reality. In the face of the powerful immune system of the human body, the virus also needs to "fight in regiments". Thousands and tens of thousands of viruses can attack a little at the same time before they can tear open the body's immune system. Therefore, the larger the viral particles, the more viruses they carry, and the more dangerous they are. But the larger the particles, the easier it is to be blocked by BFE99 masks, even very basic masks.
If a mask can filter more than 95% of particulate matter, it is enough for daily protection. In addition, BFE99 masks are not thicker or the more layers, the higher the efficiency. The actual measurement shows that simply superimposing the number of layers of masks has a limited impact on the filtration efficiency. The superimposed thickness of the electret material is large, which affects the dust holding capacity, that is, the total life of the BFE99 mask, rather than the filtration efficiency. However, after the number of layers is increased, the breathing resistance will increase.
Through the above introduction and analysis of the use of BFE99, hope it helps you.
