Question

Quizplus · Accepted Answer

A paper filter that fits over your nose and mouth to block small airborne particles is typically called a face mask or surgical mask, not a mist respirator. Mist respirators are more specialized devices designed to protect against specific types of mists or aerosols, and they often have a more complex design than a simple paper filter.
