Surgical Mask - an overview | ScienceDirect Topics
Surgical masks (also known as medical masks) are fluid resistant and often used for droplet precautions, because they are designed to block large particles, but are less effective in blocking small particle aerosols (<5 μm). Surgical masks provide a barrier to prevent droplets reaching the wearer’s nose, mouth, and respiratory tract.
