Can KN95 masks be reused?
After the outbreak of the new coronavirus, masks, as the first artifact of self-protection and isolation, have faintly upgraded from ordinary medical consumables to strategic materials. At this stage, masks are indeed not enough, and they are seriously out of stock. It is an objective reality that masks are not enough for the time being, but we can use our brains to overcome difficulties. Reusing masks is the best way.When reusing, you must remember: don't touch the water!

If the protective ability of a 3-layer cotton mask is defined as 5, the protective ability of that layer of KN95 mask is 100, which is extremely different. If your ears are wide enough, wearing a 60-layer cotton mask is equivalent to someone else wearing a KN95 mask.

KN95 Face Mask

The KN95 mask has a filtering effect of greater than or equal to 95% for particles with a diameter of 0.3 µm, which is extremely overbearing. Why is this kind of mask so magical, is its mesh particularly fine? Don't be kidding, it's impossible to make such a fine mesh with any material, which is in the micron level. In other words, even if you do it, I'm afraid you won't be able to breathe. With such a small mesh, the airflow can't get in at all.

KN95 can have such a strong protection ability, the core secret lies in the principle of electrostatic adsorption. Tear open the KN95 mask, inside is a layer of meltblown non-woven fabric. This kind of meltblown non-woven fabric is made of polypropylene, which is a kind of ultra-fine electrostatic fiber. The biggest feature is that after electret treatment, it will have electrostatic adsorption capacity. When the airflow you breathe passes through the non-woven fabric, the air passes normally, and all the dust and toxic droplets are absorbed by static electricity. If you think about the way your hair is adsorbed by sweaters in winter, you probably know the principle of KN95 protection. After air dust is adsorbed by static electricity, it is extremely difficult to detach, and there is no way to clean it. As long as the static electricity is there, the dust and germs will always be there. If the static electricity is gone, then the mask will be useless and become an ordinary cotton mask.

In virus-intensive places such as hospitals, KN95 masks are for one-time use. Because masks are densely packed with viruses, it is extremely unsafe to reuse them. They must be destroyed immediately after they are taken off. However, the density of the virus that ordinary people are exposed to is very low, and there is no need to be so vigilant. This precious mask can be reused.
