About mask standards: The N series is an American standard, KN. Series is Chinese standard, The fact-finding mission series are European standards, The higher the number, the higher the protection level. It is easier to understand with a formula: Ffp3> Ffp2 = N95 = KN95> KN90 A V at the end of the number indicates a valve All 95 and 90 starts with the N95 series The n90 series also works as n95., In general, to resist viruses and flu, the N95 and n 90 series is sufficient 2. Medical N95 and n90 masks can prevent high-pressure liquid splashing , so they have higher standards than ordinary N95 and n90 models most commonly used medical protective masks. In addition, there are children's models in 1860. Ordinary people or medical personnel who are not exposed to high-pressure liquid splashes can choose ordinary N95 and n90 masks that meet the standards of the Noysh language. 3. European manufacturers of Ffp2 standard masks include Germany's UVEX, etc .; Ffp3 is a higher level (99) protective mask. 4. The Chinese standard GB2626-2006 refers to the standard of standard KN95 and kn90 masks, and the standard of medical KN95 masks is GB19083-2010. (Similarly, ordinary people and medical personnel who are not exposed to high-pressure liquid splashes can use ordinary KN95 or kn 90 masks.) 5. Another common question is whether to choose a mask with or without a valve? Ordinary masks with valves are more comfortable. Medical masks are not allowed to have valves. When ordinary people are infected or suspected to be infected, a medical mask without a valve must be selected. 6.
