Dust masks are simple protective devices designed to cover the nose and mouth, helping to filter out dust, pollen, and other airborne particles. They are commonly used in various settings, such as construction sites, woodworking shops, and during activities like gardening. Dust masks are typically made from lightweight materials and are often disposable. These masks are not designed to protect against harmful gases or vapors, so they are different from respirators, which offer a higher level of protection. When choosing a dust mask, it is important to ensure a proper fit to maximize effectiveness and comfort during use.
