Product Description. This like-new Czech CM3 gas mask helps to protect the face, eyes and respiratory system against chemicals and radioactive and biological warfare agents that are used in the form of gases, vapors, aerosols, etc. Includes bag and filter.
Some gas masks are also respirators, though the word gas mask is often used to refer to military equipment (e.g. field protective mask). The user of the gas mask is not protected from gas that the skin can absorb. Most gas mask filters will last around 24 hours in a nuclear biological chemical (NBC) situation.
