The main role of activated carbon masks is to be able to block the absorption of harmful gases and dust and other particles by the human body, because activated carbon has a relatively strong adsorption effect and can be absorbed before the absorption of harmful substances by the human body, but whether activated carbon masks can protect against this new coronavirus, experts have given clearer guidance, the general public gives priority to medical surgical masks and medical protective masks, etc. These masks can better prevent and block the new coronavirus pneumonia. Because surgical masks and medical masks have relatively clear requirements for blocking droplet transmission as well as permeability, because to achieve medical use, in the absence of a mask, you can properly choose such as activated charcoal, cotton masks and other masks, but the protective effect of masks will be greatly reduced, it is best to use medical masks, and it is appropriate to go out as little as possible.
