Coronavirus spreads 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. Contact with body fluids splashed from coughing or sneezing from an infected person, or shaking hands with an infected person may cause infection. If you touch something that an infected person has touched with your hand, and then touch your own mouth, nose, or eyes, you can also spread the virus. You must wear a mask, even if you are in contact with an infected person, wearing a Kn95 Mask Protection Breathable Metal Strip can prevent you from directly inhaling the virus in the droplets.

Under normal circumstances, there is about 1 liter of liquid in a person’s lungs. Every time you sneeze, your lungs will spray this liquid into a mist like a squeezed mineral water bottle. When outside the body, they are divided into more than 40,000 small drops, each of which contains a large number of viruses and bacteria. Due to the huge thrust in the body, the speed of these liquids can be as high as 35 meters per second, and the propagation distance can reach 3 to 8 meters.

Be sure to wash your hands frequently, even if the virus is left on your hands, washing your hands can block the virus from entering the body through your hands.

N95 mask is actually a respirator. Respirator is a kind of respiratory protection equipment. Compared with ordinary masks, it fits the face tighter in design and can filter particles in the air very effectively. Among them, N means Not resistant to oil, which can be used to protect non-oily suspended particles; 95 means that the filtration efficiency is greater than or equal to 95%, indicating that after careful testing, this respirator can block at least 95% of very small (0.3 Micron level) test particles.

In terms of design, if ranked according to the priority of the wearer's own protection capabilities (from high to low): N95 masks>surgical masks>ordinary medical masks>ordinary cotton masks.

If worn correctly, the filtering capacity of N95 is better than that of ordinary masks and medical masks. However, even if it is worn in full compliance with the requirements, it cannot 100% eliminate the risk of infection or death.

Kn95 Mask Protection Breathable Metal Strip can filter 95% virus.KN95 is one of the levels specified in the Chinese standard GB2626-2006, and N95 is one of the levels specified in the American standard 42 CFR 84. The technical requirements and test methods of these two levels are basically the same, and the filtration efficiency reaches 95% under the corresponding standards.
