How masks protect against coronavirus?

Coronavirus is transmitted from person to person by contacting the body fluid splashed by an infected person’s cough or sneeze, or shaking hands with the infected person, which may lead to infection; if your hands touch something the infected person has touched, and then touch your own mouth, nose or eyes, you may also transmit the virus.

Wearing a non woven face mask is the basic means of de ng against the new coronavirus. Masks generally have three layers, from the outside to the inside are the waterproof layer, the filter layer, and the comfort layer. The waterproof layer is a layer of polypropylene spunbond non-woven fabric, which can effectively blocks the visible objects such as droplets. The filter layer is a layer of melt-blown non-woven fabric, which has high strength and strong filtering ability, and has excellent capture ability to micro and nano particles such as fine dust and bacteria in the air, which can effectively prevent the penetration of bacteria and liquid, but can be breathable;  it can prevent cross-infection and reduce the shedding of dust and hair. The comfort layer is also polypropylene spunbond non-woven fabric, which makes the skin dry and comfortable.

Medical face masks, especially KN95 masks, can filter particles in the air very effectively, prevent droplet infection caused by the patient's body fluids or blood splashes (droplets are 1 to 5 microns in diameter), and are suitable for protecting respiratory infectious diseases transmitted by air. In addition to blocking droplet infection, masks also prevent your hands from directly touching your nose and mouth, which block the transmission path of the coronavirus, and of course it can also resist the coronavirus to a certain extent.
