There is not much difference in the level of protection between N95 masks and medical masks.
N95 masks have a preference for isolation compared to disposable medical masks. It is best for healthcare workers to choose medical masks or N95 masks, as N95 masks can only isolate viruses on the surface of the mask. It is recommended not to excessively compress the mask when wearing it to avoid virus droplets getting wet through the mask, which can easily cause virus infection.
If the epidemic situation is severe in an area or when there is a lot of contact with confirmed patients, it is best to wear N95 masks for safety. Wearing masks requires distinguishing between the front and back, and not wearing them backwards, as wearing them backwards can affect the isolation effect.
