Components of disposable gas masks

The structure of disposable anti-virus masks should be divided into two parts, one is the main body of the mask, which is a mask frame; the other is the filter material part, including filter cotton for dust prevention and chemical filter box for anti-virus. 

When dust prevention is required in a dusty working environment, a dust-proof mask is matched with the corresponding filter cotton; when it is necessary to perform anti-virus in a toxic environment, replace the filter cotton and install the corresponding chemical filter box , So it becomes a gas mask again.
