Activities like sanding, welding, painting, or even repairs can decrease your air quality, possibly putting your health at risk. Instead of allowing harmful airborne irritants to make their way into your mouth, nose, throat, or lungs, you should use a respirator. Respirators fit over your nose and mouth to form an air filter to reduce the number of particles and vapors you inhale. Respirators are classified by the type of hazard they protect against, their APF and the specific substance(s) they’re approved for.
