Dust mask

A dust mask is a flexible paper pad held over the nose and mouth made for protection against chronically toxic nuisance dusts, like from occupational exposure to plant dusts like hay. They are not intended to provide protection from most airborne hazards. The European FFP1 mask, the lowest-grade standard available in the jurisdiction, is an example of a dust mask, being only certified to remove ~80% of dusts and mists.

Dust masks are used in environments with dusts encountered during construction or cleaning activities, biological hazards from farming, or sweeping. A dust mask can also be worn in environments with allergens such as tree and grass pollen.
