3 Ply Mask

3 Ply mask also known as surgical mask is worn to prevent airborne transmission of infections by blocking the transmission of pathogens primarily bacteria and viruses shed in respiratory droplets and aerosols from the wearer’s mouth and nose. They act as an additional barrier for the airway and are not usually designed to completely prevent the wearer from inhaling smaller airborne bacteria or viruses, but could be still protective by filtering out and trapping most of the droplets that carry them. There is a predominance of evidence that surgical masks protect both the wearer and persons near the wearer from the spreading of viruses. Surgical masks are made of a nonwoven fabric created using a melt blowing process.
