The number of covid-19 infections continues to increase. The most effective way to prevent covid-19 is to go to places with fewer people and wash your hands frequently. If you must go out, you need to wear a mask. Regarding masks, people are more keen to choose N95 or KN95 masks, so can this KN95 mask really protect against viruses?
First of all, it can be said with certainty that KN95 masks are anti-virus. KN95 masks are similar to N95 masks, except that one is a Chinese standard and the other is an American standard.
If there are two numbers of 95, it means that the protective ability of this mask is more than 95%. That is to say, for tiny substances larger than 0.3 micrometers, the mask has a defensive ability of more than 95%, and it can block tiny substances larger than 0.3 micrometers outside the mask. Viruses and bacteria are generally larger than 0.7 micrometers. Therefore, using a mask such as KN95 can effectively protect against viruses.

Why wear a mask!
Coronaviruses are transmitted from person to person, usually when someone comes into contact with the secretions of an infected person. The infectivity of the virus directly affects the route of transmission. The current transmission of the new coronavirus is unclear, but according to past experience, contact with infected body fluids caused by coughing or sneezing, or shaking hands with infected persons may cause infection. The virus can also be transmitted if your hands touch something the infected person has touched and then touch your own mouth, nose, or eyes.
Under normal circumstances, a person's lungs will have about 1 liter of liquid, and each time they sneeze, the lungs will spray these liquids out like a squeezed mineral water bottle. Once in vitro, they are divided into more than 40,000 small drops, each containing a large amount of viruses and bacteria. Due to the huge thrust in the body, these liquids can reach speeds of up to 35 meters per second, and the propagation distance can reach 3 to 8 meters.
The reason why SARS in 2003 was so terrible was that it was difficult for people to control the speed at which it was transmitted through droplets. Southeast Asian influenza Monday, went to South China next Monday, and spread across the country next Monday.
So be sure to wear a mask! !! !! Even if you come in contact with an infected person, wearing a mask can stop you from inhaling the virus in the droplets directly.
Be sure to wash your hands frequently! !! !! Even if the virus is left on your hands, washing your hands can prevent the virus from entering your body through your hands.
