What defenses can we take during the coronavirus? Are masks a must-have item? The following is an introduction to how we should protect ourselves and our families during the epidemic.
During the epidemic of the new coronavirus, you can wear N95 medical masks, which is more effective in preventing new coronavirus;
Secondly, medical surgical masks can also be used, which can also play a role in preventing new coronavirus.
So, what are the benefits of wearing a mask during the epidemic of the new coronavirus?
During the Coronavirus epidemic, everyone should strengthen exercise, work regularly, and improve their immunity; pay attention to maintaining indoor air circulation, avoiding closed and airless public places and places where people are concentrated, and wear masks when necessary; after going home, Wash your hands and nose in time.
1. Wear medical surgical masks.
Masks work by blocking the source of the virus by isolating tiny particles. The earliest masks were mainly gauze when they first appeared, but nowadays medical masks generally use polypropylene meltblown cloth. Meltblown cloth is mainly a structured loose material with a pore size of 1-5 microns, which also has good air permeability, so it is often used as a raw material for masks.
Coronavirus is not transmitted by itself during the transmission process. It is often transmitted through the air through breathing, chatting, coughing, and sneezing. Although surgical masks look thin, they can withstand more than 90% of droplets. Because the filter cloth of medical masks has a certain function to resist bacteria and viruses (but this is definitely not absolute protection).
2.There is also a mask called N95 that everyone must have heard. The filtration efficiency of KN95 masks for the most easily penetrated particles is 95%, and the diameter of the most easily penetrated particles is 0.3 microns, which is larger or smaller than it Are easily intercepted.
Coronaviruses are generally around 0.1 microns in diameter. Coronaviruses are transmitted through droplets. The droplets are 1-5 microns in diameter. Both KN95 masks can protect.
