What does a dust mask protect?

Dust masks, also known as particulate respirators, protect wearers from inhaling hazardous airborne particles, such as dust, smoke, and certain types of pathogens. They cover the nose and mouth and are designed to filter out particles before they reach the respiratory system. Dust masks are commonly used in various industries, construction sites, healthcare settings, and during activities like cleaning, sanding, or working with dusty materials. They offer protection against solid particles but are not effective in filtering gases or vapors.
