Question

With a negative pressure respirator, when you inhale, you pull air through a filter and when you exhale, a valve allows your used air to escape.

Answer 1

Answer: Yes.

Explanation:

By properly fitting a respirator on the face, when we gently breathe in the air, the filter in the respirator will prevent harmful substances in the air from entering the respirator to our lungs. A negative pressure respirator shows that the air pressure inside the mask is less than the air pressure outside the mask, which is when we are breathing in.

On the other hand, the positive pressure respirator happens when we breathe out whereby a slight pressure will build up inside the respirator, then the air will pass through the exhalation valve to exit the respirator.
