A gas mask is a type of respirator worn over the face to protect the wearer from airborne pollutants and toxic gases. It functions by forming a seal around the face, preventing contaminated air from entering the respiratory system. The air is instead drawn through a filter or canister that removes specific contaminants before it can be inhaled.

Gas masks are designed for various purposes and can protect against a wide range of hazards, including chemical warfare agents, industrial chemicals, smoke, and biological agents. The type of filter or canister used is crucial and depends on the specific threat it is intended to counter. For instance, filters designed for organic vapors will differ from those meant to neutralize acid gases.

Historically, gas masks were developed in response to the use of chemical weapons in warfare. Early designs were often cumbersome and provided limited protection. Over time, materials and filtration technologies have advanced significantly, leading to more effective and user-friendly designs. Modern gas masks are used not only in military contexts but also by emergency responders, industrial workers in hazardous environments, and even in some civilian applications where air quality is a concern. Proper fit and maintenance are essential for a gas mask to provide effective protection.
