Original title: Can GB2626 masks that meet the KN95 standard be used? Recently, a series of rumors have appeared on the Internet. One of them is that the masks produced according to the GB2626 standard and KN95 are industrial dust masks, not the GB19083 standard for medical masks. They do not prevent germs and are useless to wear. There are also some GB2626 masks that are not as good as surgical mask and so on. So what is the truth? Let's analyze it in detail: First of all, there is an important indicator of the mask to prevent viruses,Full Body Disposable Coverall, which is the filtration of non-oily particles. The technical standard used in the surgical mask is YY0469, and the filtration of non-oily particles is greater than or equal to 30%. GB2626 masks have three types of non-oily particulate matter filtration, KN90 ≥ 90%; KN95 ≥ 95%; KN100 ≥ 99.97%. The N95 mask we often talk about is actually the KN95 mask of GB2626. Expand the full text GB19083 masks are generally medical protective masks,free shipping disposable coverall, which are used in fever clinics and places where patients are in direct contact, and need to be used with goggles and other devices. There are also three types, but the three types of medical protective masks are called level 1, KN95 Face Mask ,KN95 Mask for Epidemic Prevention and Control, level 2 and level 3. The non-oily filtration index of GB19083 medical protective mask is higher than the three levels of GB2626 KN standard mask. The lowest level 1 is equivalent to KN95, which is why KN95 masks are recommended. Not to mention the medical surgical mask, the filtration of non-oily particles is greater than or equal to 30%, which is far behind (experts say that KN95 can not be bought, medical surgical mask can also be worn, better than not). It can be seen from the following table that for virus prevention, according to the filtration index of non-oily particles, GB2626 = GB 19083 > YY0469. The difference is that surgical mask and medical protective masks have more indicators such as blood penetration and surface moisture resistance, which provide protection for medical workers during blood splashing and body fluid splashing. To sum up, the up owner will sum up. From the perspective of virus prevention for ordinary people, GB2626 and GB19083 are exactly the same. If you care about the additional liquidproof requirements of GB 19083 in the form, I just want to say that you should wear goggles and biochemical suits, after all, this virus can be transmitted from the eyes. Warm Reminder: About the exhalation valve. Healthy people really can't buy masks without exhalation valves,Medical Full Body Coverall, so they can wear exhalation valve masks to protect themselves. Under the same standard, the protective effect of the two masks is the same. Those who are suspected to be ill and want to go to hospitals and other public places to see a doctor must not wear masks with exhalation valves. You can see that the Red Cross has indicated that medical consumables should have no air valve. Finally, let's give a compliment to the great medical staff working in the front line in Wuhan!
