Can KN95 Protective Masks Be Reused?

The kn95 nanofiber mask has been put into mass production. Nanofiber masks are more powerful to listen to, so what is it like? From the appearance, it is similar to ordinary masks,KN95 Protective Mask with a layer of cloth on both sides. But the key point is that a layer of nanofibers is used in the middle of the two layers of cloth. It is such a paper-like thing. It is very thin and light. It can even transmit light. It can be easily scraped off by grinding it with a hand. Layer,KN95 Protective Mask this layer is the nanofiber. The fiber diameter is thinner and can reach about one hundred nanometers.

The nanofibers under the microscope are shown this way. And it shows the comparison with ordinary non-woven fabric fibers. Such thin,KN95 Protective Mask spider-like webs are nano-fibers. Since the diameter of a general virus is between 100 and 200 nanometers, such nanofibers can directly isolate the virus.

95 protective mask / N95 Mask: This mask can block more than 95% of sub-micron particles,KN95 Protective Mask but the respiratory impedance is higher,KN95 Protective Mask such as the resistance of inhalation and exhalation increase by 26% and 22%, so it is not suitable for long-term use; The American Medical Journal reported that there is no significant difference between it and surgical masks in preventing influenza.

N95 masks and breathing valves. As for whether the masks have breathing valves or not,KN95 Protective Mask the difference is not much. The most important function of preventing viruses is the same. However,KN95 Protective Mask breathing with a valve will be more comfortable,KN95 Protective Mask but if it is a virus infection, it should not be Choose N95 with a breathing valve, because the valve will discharge the patient's virus.

Respiratory valve principle: There are also various masks produced by different manufacturers,KN95 Protective Mask such as three-dimensional masks,KN95 Protective Mask whose three-dimensional structure can reduce the pressure on the ears, and greatly reduce the trouble of glasses fogging,KN95 Protective Mask suitable for long-term wear; Block particles in the air with a particle size less than or equal to 2.5 microns, PM2.5 refers to suspended particles with a diameter of less than 2.5 microns;KN95 Protective Mask and nanofiber masks, etc .;
