N95 respirators are specialized masks designed to filter out at least 95% of airborne particles, including dust, smoke, and viruses. They fit tightly to the face, creating a seal that helps prevent unfiltered air from entering. This makes them more effective than standard surgical masks in protecting the wearer from harmful substances. These respirators are commonly used in healthcare settings, especially during outbreaks of infectious diseases like COVID-19. They are also utilized in industries where workers are exposed to hazardous materials. Proper fitting and usage are essential for maximizing their protective capabilities.
