These 3Ply Face Masks Intended to cover the nose and mouth. Also known as theatre masks or surgical masks.
A 3 ply surgical mask is a type of disposable medical equipment that covers the mouth and nose, worn by people who are in contact with patients or other individuals during flu seasons. It consists of three layers: an inner cotton layer to filter air coming through it, followed by two outer layers made from rubberized fabric material that act as a barrier against droplets sprayed into the air.
People use them to prevent the spread of infectious diseases like influenza or chickenpox when they come into contact with someone who has those illnesses. They also protect users from breathing in airborne bacteria that can cause respiratory problems such as chronic obstructive pulmonary disease (COPD). Doctors recommended wearing one if you have symptoms yourself because this will reduce your chance of transmitting covid19.
Disclaimer: Mask will not guarantee protection against Covid-19 illness but will act as a deterrent to touching your face and limit spreading the virus.
