Dust mask
mask to protect from dust
A dust mask is a type of mask that is used to protect someone from dust that might hurt them. Some say it is a respirator. But a dust mask lets a lot of dust in. This is not like most respirators.[1][2]

This is also not like a N95. A N95 has to be checked with a harder NIOSH rating. NIOSH used to check dust masks. When 42 CFR Part 84 was made, NIOSH stopped checking dust masks.[3]
In Europe, governments still check dust masks. They check dust masks under FFP1 rules. FFP1 is the lowest FFP rule. It lets 22% of air go by the filter. The filter here is the dust mask.[4]
Tuberculosis and viruses can go past a dust mask to the nose and mouth.[5]
