A face mask is a protective covering designed to be worn over the nose and mouth to filter out airborne particles, contaminants, or pathogens, thereby reducing the spread of infections or exposure to pollutants. It can be made from various materials, including cloth, paper, or specialized fabrics, and is commonly used in medical, industrial, and public settings. Face masks come in different types, such as surgical masks, N95 respirators, and reusable cloth masks.
