Disposable face masks work by acting as a physical barrier between the wearer's mouth, nose, and the surrounding environment. They are typically made of a non-woven fabric that is designed to filter out particles, droplets, and other contaminants. The fabric used in these masks has multiple layers that work together to trap and reduce the passage of airborne particles or droplets that may contain viruses or bacteria. When worn properly, the mask covers the nose and mouth, preventing the release of respiratory droplets from the wearer and reducing the risk of inhaling harmful particles from the environment.
