Dust masks are also known as “disposable dust respirators” and their primary purpose is to protect technicians from many dangerous or harmful substances in form of dust, mist, or fumes that are present while performing headlight restorations.
When used properly, a dust mask prevents the inhalation of dust in the air and protects the lungs. When you inhale, air is pulled through the dust mask and dust is captured on the outside of the mask.
It’s better to be safe than sorry so always wear a dust mask while performing headlight restorations. Working with a dust mask can provide added protection from foreign matter that may damage your lungs.
