How does a mitarly NBC gas mask work?

A military NBC (Nuclear, Biological, Chemical) gas mask works by utilizing a combination of filtration and sealing technologies to protect the wearer from harmful agents. The mask features a tight-fitting design to create a secure seal around the face, preventing contaminants from entering. It incorporates filters that contain activated carbon and other materials to absorb and neutralize toxic gases, aerosols, and biological agents. Additionally, some masks may have a drinking system and panoramic lenses for enhanced visibility and functionality in hazardous environments.
