1, the standard is not the same
difference between n95 and kn95 mask machine is the United States standard and Chinese standard. N95 and KN95 masks have a layer of anti-bacterial cloth inside, which can play a role in the anti-virus function of the main material.
2, the grade is not the same
N95 is the U.S. respirator grade, by the U.S. National Institute for Occupational Safety and Health (NIOSH). These masks are capable of filtering out more than 95% of non-oil particulate matter (aerosols) under the specified air flow rate (85L/min), hence the name N95, while if they are capable of filtering out more than 99% of particulate matter (aerosols), they are called N99 masks.
Additionally, corresponding to N95, KN95 is a mask that has been standardized by China's GB2626-2006 respiratory protective equipment self-priming filtering anti-particulate respirator. However, KN95 and N95 mask protection level is comparable, both for non-oil particulate matter (experimental sodium chloride particulate matter) protection efficiency are not less than 95%.
n95 and kn95 which effect is good
1, n95 and kn95 in the particulate matter filtration efficiency is the same, as for, n95 and kn95 which effect is good, in fact, their protective effect is actually the same. kn95 is our country for the particulate matter filtration effect of this type of mask, n95 mask is actually the United States of America. The n95 mask is actually a test standard of the United States, so the two are just different countries, the use of code is not the same.
2, n95 and kn95 effect is the same, and there is no one more than another statement, in fact, Mr. Zhong Nanshan also said, in daily life out of the ordinary disposable medical masks are completely enough, it can help us to block off the air droplets, residual harmful substances.
3, now n95 and kn95 masks are still quite scarce, can buy n95 and kn95 masks is naturally better, did not grab a friend to buy disposable medical masks can be, go out and be sure to wear a mask, protect their health and safety.
There are no washable n95 masks
1, there are no washable n95 masks, N95 masks can not be washed, if the N95 mask washed after repeated use, easy to destroy the structure of the filter cotton, resulting in poor protection. That is to say, after washing the N95 mask is not to play a protective role.
2, in fact, is not a serious epidemic area, we use disposable medical masks can also play a role in preventing viruses, usually do not need to wear N95 masks. For example, in the case of not many people and no direct contact with patients with new coronavirus pneumonia, wear disposable masks can be.
n95 mask can be reused
1, n95 mask can be reused? In general, have not been to the hospital, or have not been to the place of dense traffic, N95 masks can be used repeatedly. Generally can be used for 1-2 days or about 5 times.
2, if the N95 mask is labeled with the words single-use, then, after use can not be reused. If you reuse it, it won't work to protect you.
3, N95 masks can not be cleaned or reused, under normal circumstances, if it is used outdoors, such as subway, public transportation, supermarkets, shopping malls and other public **** place, N95 level mouth need 4-6 hours to replace one, but if it is in the new pneumonia virus infected areas, it is recommended that 2 hours in time to replace one.
