A dust mask is a type of protective gear designed to cover the nose and mouth, helping to filter out harmful particles from the air. It is commonly used in various settings, such as construction sites, woodworking, and during activities that generate dust, like sanding or sweeping. Dust masks are typically made from lightweight materials and are often disposable. These masks are not the same as respirators, which provide a higher level of protection against airborne contaminants. While dust masks can help reduce exposure to dust, pollen, and other irritants, they may not be effective against smaller particles or toxic substances.
