Do you know the difference between medical protective masks, N95 masks and KN95 masks? Next, the editor will tell you.
First of all, let's talk about medical protective masks. Medical protective masks are in line with China's GB 19083-2010 mandatory standard, and the filtration efficiency is greater than or equal to 95 percent. And it is required to pass the synthetic blood penetration test (to prevent body fluid splashing), and it is required to meet the Microbial indicators.
Next, let's talk about the N95 mask. It is certified by NIOSH in the United States, and the filtration efficiency of non-oily particulate matter is greater than or equal to 95 percent.
Then there is the KN95 mask: in line with China's GB 2626 mandatory standard, the filtration efficiency of non-oily particulate matter is greater than or equal to 95 percent.
The test methods for the filtration efficiency of the above three levels of masks are the same. Therefore, their filtration efficiency levels are also the same. KN95 non-medical masks are not suitable for medical staff.
A few things to keep in mind while wearing a mask:
1. Before we wear masks, we must develop a good habit. That is, we should wash our hands before wearing masks.
2. We need to distinguish the inside and outside of the mask, the top and bottom. It is also necessary to know that the light-colored surface is the inner surface, which should be close to the mouth and nose, and the dark-colored surface faces outward; one end of the metal strip is the top of the mask.
3. What we need to do is not to squeeze the mask with our hands.
