kn90 and Kn95 mask , uses for Corona, Ebola and others like Corona labrotory . 3layer protector and filter .inside meltblown fabric . 100% workable and safety product . 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 starts with the N95 series The 90 series also works near as n95., which is much better than ordinary masks. In general, to resist viruses and flu, the N95 and n 90 series is sufficient In view of the confusion of the choice of masks, I am afraid that donating the wrong one will not be used, here are some different standards for masks. The model and execution standard of the mask are printed on the left side of the mask. You can buy a mask according to this. First, masks are divided into three standards: The N95 type is produced according to the American standard Noish language, and the manufacturers are 3M Company and Honeywell; Ffp2 is the European standard EN149; The KN95 type and kn90 is the Chinese standard GB2626-2006, and all the three types of masks with the implementation standard printed on them are qualified masks. 2. Medical N95 masks can prevent high-pressure liquid splashing also kn90, so they have higher standards than ordinary N95 and n90 models. Taking 3M as an example, models 1860 and 9132 are the 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 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. Medical surgical masks, the common standard is Yy0469-2010, or Yy0469-2011, which is printed on the independent outer packaging of each mask. 1860 / 1870+ This model is used for medical operations, anti-moisture dust, etc. 8210/8511 This model is used for construction engineering, anti-dust, etc. 9210+ This model is used for industrial engineering, anti-dust and rot |
