Originally published as What’s the difference between N95 and KN95 masks? Can they all be used for medical protection? An epidemic has made almost everyone aware of the various standards of masks, the most popular of which are N95 and KN95. What is the difference between N95 and KN95? Can these two standard masks be used for first-line medical protection? Let’s take a look at the answer in this article. 1. Is there any difference between KN95 and N95 mask? N95 is the certification grade for respirators in the United States and is certified by the National Institute for Occupational Safety and Health (NIOSH). This kind of mask can filter out more than 95% of non-oily particles (aerosols) under the condition of specified airflow (85L/min), so it is named N95. If it can filter more than 99% of particulate matter (aerosol), it is called N99 mask. In addition, corresponding to N95, KN95 is a mask certified by China’s GB2626-2006 Respiratory Protective Equipment Self-priming Filter Particulate Respirator Standard. KN95 has the same level of protection as N95 mask, but it follows the test standards of different countries. KN95 masks follow Chinese standards and N95 mask follow American standards, both of which have a protective efficiency of no less than 95% against non-oily particles (sodium chloride particles for experiments). 2. Can KN95 mask be used for first-line protection? KN95 respirators and N95 mask include both medical and non-medical types. Among them,free shipping disposable coverall, KN95/N95 mask masks with “medical” logo can be used for first-line protection of medical staff during the anti-epidemic period, masks without “medical” logo are not recommended for medical staff, ordinary people can use them. Masks conforming to GB19083 above Grade 1 can not only achieve 95% filtration, but also prevent liquid penetration,Virus Prevention Mask 3 Ply with Earloop, and can be used for various operations in medical institutions. 3. Why is KN95/N95 mask anti-virus? Viruses usually do not exist in the air alone, but are attached to particles such as droplets, dust and dander. The filtering mechanism of KN95 and N95 mask is to block these fine particles through the high-performance filter layer in the mask to build a protective barrier. Therefore, when wearing KN95/N95 respirators, namely self-priming filter particulate respirator masks, attention should be paid to the tightness, KN95 Face Mask with Five Layers ,Against Bacteria Breathable KN95 Face Mask, which should be close to the face, and never leave a “convenient door” The problem is that it is not clear whether the mechanical switch will suddenly break down when worn,CE Certificate KN95 Mask, or whether it will be stuck by fine particles, allowing harmful particles carried by air that have not passed through the filter layer to enter. Therefore, medical masks do not have breathing valves. Return to Sohu to see more Responsible Editor:. zjyuan-group.com
