There are respirators and there are respirators. The kind we are referring to here are not the high-tech medical apparatus that assist very ill patients to breathe. We're talking about the respirator mask worn over the nose and mouth that is used to protect the throat and lungs. Made from different filtration material these PPEs strain out the bad stuff that's in the air allowing you to breathe easier—and safer. The next time you are hard at work, or play, and you sense there's “something in the air”, you might want to reach for a respirator.
