Respirator
device designed to protect the wearer from inhaling harmful dusts, fumes, vapors, or gases / From Wikipedia, the free encyclopedia
A respirator is a kind of mask that is used to protect someone from breathing in dusts, fumes, or gases that might hurt them. Respirators come in many types and sizes. They are used by the military and industrial workers. They are also used by doctors in hospitals. To keep people safe, respirators keep air going to the filter by sealing to the face. This is not like a surgical mask, which does not seal to the face. This then causes air to go by the filter.[1]
A filtering facepice respirator is a respirator that is not made of plastic or rubber. They last for a shorter time.[2]
A type of respirator is a N95.
