Excuse me, what is the difference between N95 and KN95 masks?

date:[2022-09-22 15:29:59]

Now, due to the outbreak of a new type of coronavirus, for many people, mask is necessary, especially the N95 mask, had appeared in the market out of stock, at present, there are a lot of the manufacture of mask manufacturers are working overtime, we ordinary consumers don't hoard masks, it is good enough, more important is to guarantee supplies to come more to its place, At the very least, the need for masks should be ensured for medical staff. 

However, at present, many people still have a lot of questions about the N95 and medical surgical masks, such as the difference between true and false, the difference between models, whether they can be used repeatedly, etc., so this time, we will talk about the N95 mask. 

Disinfection of Shanghai city CDC infectious disease prevention ren-yi zhu N95 and KN95 masks, gives a clear answer, he said KN95 masks for particulate matter has the filtering effect is our country face mask (greater than or equal to 95%), N95 respirator is the test standard of the United States, they are from the filtering effect of particulate matter, in fact is the same, Just a different code name. 

In addition, it is worth noting that the masks provided to medical staff are one of the N95 masks, and not all N95 masks are medical protective masks.

At the same time, Zhu Renyi also mentioned that medical workers need to wear masks for four hours a day. When breathing with masks, water vapor will be generated in the mouth and the mask will become wet. Therefore, in addition to filtering particles, medical protective masks should also be tested for synthetic blood penetration and moisture resistance.

In this problem, the KN95 and N95 masks mentioned are exactly the same in the level of protection, so you should not have any concerns at all. It will play a considerable protective role when you go out. 

2. Can the N95 mask be used repeatedly?

Now it is known that masks are very difficult to buy, and the price is also very high, so many friends have a question, that is, N95 masks can be used repeatedly? The answer is yes. 

On February 2nd, ministry vice-minister wang jiang said in an interview that masks the production capacity of about 20 million or so a day in our country, including 2.2 million medical surgical masks, medical N95 respirator capacity is 600000, so, in the case of limited capacity and the sought-after, N95 respirator is very precious, so, it can be repeatedly used, It can also be very effective in relieving the current pressure of the mask. 

According to the National Institute for Occupational Safety and Health, N95 masks can be reused as long as they maintain structural and functional integrity and the filter material is not physically damaged. It should be noted that the mask does not need to be sterilized during repeated use. 

When put on or take off mask, however, it is a good idea to do a good job in hand clean, or wear gloves, it can effectively make masks from pollution, because the main pollution masks risk or from the hand to touch, to mask the disinfection will to destruction of the integrity of its structure and function, it is best not to make the attempt. 

The N95 mask is already a very high level of protection for the average person, and the medical N95 has the added benefit of protecting doctors from blood spatter. Currently, N95 masks are in short supply, so reusing them is a great way to save resources. 

3. How to distinguish N95 masks from fake ones 

While, since the outbreak of a new type of coronavirus, market supervision departments at all levels and consumer advocates have called on business integrity law-abiding business, but there are also many unscrupulous businessmen against crime, the sale of fake mask, taken advantage of the illegal profit, especially in that mask once under the condition of out of stock at present, there are a lot of friends will worry, afraid oneself bought a fake mask, so, Now I would like to share some knowledge about how to distinguish fake masks from real ones.

At present, medical surgical masks and N95 masks can effectively prevent the novel coronavirus. According to the Beijing Consumers' Association, medical surgical masks have three layers of filtration. When you buy them, check whether there is the word YY0469-2011 on the package, and those meet the standards of YY0469-2011 Medical Surgical masks. Is a proper medical surgical mask. 

As for the N95 masks that we have more daily contact with, Beijing Consumers Association combined with the most popular 3M masks at present, also gave the method to distinguish the real and fake: 

1. Smell: 3M mask has no odor, it only has a light activated carbon smell, not rubber smell. 

2, look at the printing:  3 m masks the font above, all of them are laser printing, print traces of the 45 degree Angle, fake goods is printing ink, and printing ink printing ink uneven would happen often, from the point of concrete, quality goods of 3 m mask printing marks a striped, whereas false masks appear round dot, and authentic mask indicates that water code on the package can correspond, Fakes do not.

3, see the logo and certification: 

The LA logo and QS certification are not printed on the box, but there are two small labels, non-domestic masks, as long as the regular import, must also have LA certification, and domestic masks must have QS and LA certification.

Write in the last

Everyone is well aware of the need to wear masks to protect themselves. However, in the face of the epidemic, it is more important to protect ourselves, reduce the risk of respiratory infections and fight the epidemic with greater intensity. However, for ordinary people, allowing limited N95 masks to show their power on the battlefield and ensure the safety of medical workers has a far greater effect on the epidemic than wearing masks themselves. In addition, the more prepared the frontline is, the more leisurely ordinary consumers can buy masks.

The fight against the virus is a scientific battle. We ordinary people should not only protect ourselves, but also not cause trouble to the country. We should go out as little as possible according to the national regulations, and take protective measures when we go out.
