gas masks

A gas mask is a protective device designed to filter harmful airborne substances, such as gases, vapors, and particulates, to help maintain safe breathing environments. It covers the nose and mouth (and sometimes the eyes), typically equipped with a filter cartridge containing activated charcoal and other materials that trap or neutralize dangerous particles. When worn properly, a gas mask creates a seal to prevent contaminated air from entering and directs clean air through the filter. Used in military, industrial, and emergency scenarios, gas masks are vital for safeguarding respiratory health in hazardous conditions.
