What is the difference between N95 and KN95 masks? (17th Nov 22 at 12:48am UTC)
Original title: What is the difference between N95 and KN95 masks? Now, due to the outbreak of the new coronavirus, for many people, masks have become a necessity, especially N95 mask, the market has been out of stock. At present, many mask manufacturers are working overtime to make them. We ordinary consumers should not hoard masks, just enough. More importantly, we should ensure that materials can come to more places where they are needed. At least ensure the demand for masks for medical staff. However, at present, many people still have many questions about N95 and its surgical mask, such as the distinction between true and false, the distinction between models, whether it can be used repeatedly, and so on, so this time we will talk about the N95 mask. Zhu Renyi, Director of Disinfection Department of Shanghai CDC Infectious Disease Prevention and Control Institute, gave a clear answer to N95 and KN95 masks. He said that KN95 masks are the masks with filtering effect for particulate matter in our country (greater than or equal to 95%), and the N95 mask is the test standard of the United States. They are actually the same from the filtering effect of particulate matter. It's just a different code. In addition,Medical Full Body Coverall, it is worth noting that the mask equipped for medical staff is one of the N95, and not all N95 mask are medical protective masks. At the same time, Zhu Renyi also mentioned that the masks worn by medical staff should be worn for four hours a day. When breathing with masks, the mouth will produce water vapor, and the masks will be wet. Therefore, medical protective masks, in addition to filtering particulate matter, also need to do synthetic blood penetration tests and moisture resistance tests. In this question,KN95 Face Mask, the KN95 and the N95 mask mentioned are exactly the same in terms of protection level, so don't worry at all, wearing them when you go out will play a considerable protective role. Can N95 mask be used repeatedly? Now it is known that masks are very difficult to buy, and the price is very high, so many friends have doubts, that is, can N95 mask be used repeatedly? The answer is yes. On February 2, Wang Jiang, Vice Minister of Industry and Information Technology, said in an interview that the production capacity of masks in China is about 20 million per day, of which 2.2 million are surgical mask and 600000 are medical N95 mask. Therefore, in the case of limited production capacity and current shortage, N95 mask is very precious. Therefore, KN95 Mask with Fast Shipping ,Medical Disposable Coverall, it can be used repeatedly. It can also effectively relieve the pressure of the current mask. According to the National Institute for Occupational Safety and Health, N95 mask can be reused as long as their structure and function remain intact and the filter material is not physically damaged. It should be noted that there is no need to disinfect the masks during repeated use. However, when putting on or taking off the mask, it is better to do a good job of hand cleaning or wear gloves, which can effectively prevent the mask from being contaminated, because the main risk of contamination of the mask still comes from the touch of the hand, and the disinfection of the mask will destroy its structural and functional integrity, so it is better not to make such an attempt. For ordinary people, the protection level of N95 mask is already very high, while the medical N95 will additionally protect doctors from splashing blood. At present, N95 mask is very scarce, so repeated use can effectively save resources. 3. How to distinguish between true and false N95 mask? Although, since the outbreak of the new coronavirus, market supervision departments at all levels and consumer associations have called on businesses to operate in good faith and abide by the law, there are still many unscrupulous businessmen who commit crimes against the wind, sell fake masks and take the opportunity to make illegal profits. Especially in the current situation that masks are out of stock for a time, many friends will worry that they have bought fake masks. Now the author will share some knowledge to distinguish the true and false masks.
Expand the full text From the current point of view, the effective prevention of new coronavirus masks are surgical mask and N95 mask. According to the Beijing Consumer Association, the surgical mask has three layers of filtration. When you buy it, you can confirm whether there are YY0469-2011 words on the package, and it meets the standard of YY0469-2011 surgical mask. Is a regular medical surgical mask. For our daily contact with more N95 mask, the Beijing Consumer Association, combined with the most popular 3m masks at present, also gives a way to distinguish the true from the false: 1.

Look at printing: 3m masks above the font, all are laser printing, printing traces show 45 degrees oblique angle, fake is ink printing, and often ink printing will appear uneven ink, from a specific point of view, genuine 3m masks printing traces show stripes, while fake masks show dots, and genuine masks show and packaging. Fakes can't. 3. Look at the logo and certification: LA logo and QS certification are not printed on the box, but there are two small labels. Non-domestic masks, as long as they are imported regularly, must also have LA certification, while domestic masks must have QS and LA certification. Write at the end Everyone knows that wearing masks to protect themselves, but in the face of the epidemic, it is more important to protect themselves, reduce the risk of respiratory tract infection, and resist the epidemic with greater intensity. For ordinary people, let the limited N95 mask go to the frontline battlefield to show their power and ensure the safety of medical staff, which is far more effective than wearing masks on the epidemic. Moreover,KN95 Face Mask, the more sufficient the first-line combat readiness is, the more leisurely ordinary consumers can buy masks. Fighting against the virus is a scientific battle.
