This year, novel Coronavirus was infected with pneumonia epidemic, affecting the sensitive nerves of Chinese people. Under the constant appeal of medical experts, people pay more and more attention to the cognition of masks. Mask is a kind of hygienic product, which is worn on the position of the mouth and nose to filter the air entering the mouth and nose, so as to prevent harmful gases, smells and droplets from entering and leaving the wearer's mouth and nose. It is made of gauze or paper. In the respiratory infectious disease epidemic, in the dust and other pollution of the environment, wearing a mask has a very good effect. But here's the question: Take commuting to work: I use a disposable mask, I use it every day, do I need to change it every day? Isn't that wasteful?
Q: What are disposable masks and why can't masks be washed and reused?
Answer: because general disposable masks are made of non-woven fabrics, most of the fabrics used are disposable fabrics. So it's best to throw it away after use. Reuse is not recommended. The filter material used in disposable masks cannot be washed because of the bacteria and tiny particles adsorbed on the filter material through electrostatic action. After washing, the static electricity effect is not ideal, so it is easy to cause bacteria or small particles to enter the respiratory tract, which cannot achieve the purpose of wearing masks.
Q: Is it wasteful to use it once and throw it away?
A: Disposable masks also have a useful life. The service life of disposable masks is 4 to 8 hours. In case of contamination, deformation, damage or increased resistance, the mask should be replaced in time. Mainly with the concentration of external pollutants. The bigger the dust outside, the dirtier the air, the more stuff sticks to the filter, and the faster. Then, of course, you'll have to work harder. If the mask is only used for work and work, it can be used for many times under the condition that the mask is kept clean. It is recommended not to use the mask after 8 hours, but to replace it with a new one.
