Can anti-smog masks replace disposable medical masks?

Masks for the prevention of infectious diseases are generally classified into surgical masks, medical protective masks, and disposable medical masks. The former two are used by doctors and the latter by ordinary people. Can anti-smog masks replace disposable medical masks?

Anti-smog masks are used to prevent smog, and particulate matter in the atmosphere with excessive levels is commonly referred to as "smog", especially PM2.5, which is believed to be the "prime culprit". These small particulate matter suspended in the air for a long time, when inhaled into the respiratory tract can be harmful to health. The diameter of suspended particulate matter is 2.5 microns and less than 2.5 microns, called PM2.5. Anything below ten microns is called PM10.

Disposable medical masks are used to prevent the spread of the virus. They are nanoscale units. It can only be observed under an electron microscope.

In terms of size, anti-smog masks filter particles on the micron scale, while viruses are on the nanometer scale. Therefore, by this standard, anti-smog masks cannot filter out viruses.

However, it is important to note that virus transmission requires a host. As long as you can prevent droplets, then it must be effective in preventing virus infection!

Finally, it is important to note that wearing a mask is not enough. Because in the winter, the virus can survive for up to four hours without the human body. So, We suppose someone with the virus sneezes in an elevator, and an hour later, you get in the elevator and press the elevator and lean against the wall to look at your phone. So even if you're wearing a mask to protect yourself, you can get germs on your hands or clothes. If you don't disinfect, wash your hands, or change your clothes when you go home, you increase the risk of infection.
