Basically, disposable medical masks can only block coarse particles, and have very limited blocking effect on bacteria and fine particles such as PM2.5; a disposable mask alone is not enough to resist the lethality caused by smog, so it is not effective. In addition, disposable masks should not be used multiple times and worn for a long time when they are worn. These improper wearing methods will accelerate the production of bacteria in the masks and may also cause respiratory diseases.
Which mask to choose for anti-smog?
