Which is better, KN95 or N95

N95 masksThere is no obvious difference between it and KN95 masks, and the essence is that there are certain differences in production and testing.

N95 masks and KN95 masks have the same level of protection, but the testing standards pursued are different, the N95 masks follow the testing standards of the United States, and the KN95 masks follow the testing standards of China, both for non-oily particles, such as sodium chloride for testing.

The particles all have a good protection efficiency, 95%.

Masks KN95 and N95 have the same level of protection, but follow the test standards of different countries. The KN95 mask follows the Chinese standard, and the N95 mask follows the American standard, but the name is different, and the protection level of the mask produced according to these two standards is exactly the same, and there is no difference in the protective effect.

Masks can be divided into two categories: KP and KN according to their functions, KP is suitable for filtering oily particles, KN is suitable for filtering non-oily particles, the number after the letters is the percentage of filtration efficiency, KN95 masks mean that for non-oily particles above microns, the filtration efficiency of the mask should be greater than 95%; As for the N95 American NIOSH dust mask standard, its detailed parameters are actually the same as those of the domestic KN95.

KN95 N95 masks are also available with and without breathing valves. For masks, there is always a contradiction between breathability and filtration effect, if the filtration effect is good, it often feels more breath-holding, and the breathing valve is designed to relieve breath-holding. The exhalation valve and suction valve are a mechanical switch, the inhalation is closed, the valve is opened when exhaling, the air is "sifted" through the filter layer, and the valve is opened when exhaling to reduce the sense of resistance.

The main differences between KN95 and N95 are as follows:

1. The standards are different: KN95 is the Chinese standard GB2626-2006, and N95 is the American NIOSH-42CFR Part 84.

2. The Chinese name is different: the Chinese name of KN95 is KN95 particulate matter protective mask, and the Chinese name of N95 is N95 medical protective mask.

3. Different use scenarios: KN95 is suitable for use in high-density public places and high-risk environments, while N95 is mostly used for medical staff.

To put it simply, these two masks are two sides of the same coin, belonging to the same kind of mask, but the name is different, and the certification standards are different, one is a domestic standard, and the other is a foreign standard. The level of protection is exactly the same, and there is no difference in the protection effect.

N95 masks

KN95 mask is China's national standard GB2626-2006 classification of anti-particulate masks, from August 1, 2009 implementation of the national standard GB2626-2006 "respiratory protective equipment self-priming filter anti-particulate matter respirator" dust masks are divided into three levels: KN90, KN95, KN100.

KN95 mask.

N95 mask refers to one of the anti-particulate masks certified by NIOSH (American Institute for Occupational Safety and Health), "N" refers to non-oily suspended particulates, usually non-oily particulate matter refers to coal dust, cement dust, acid mist, microorganisms, etc., as well as talking or coughing droplets are also non-oily. "95" refers to a class of masks that filter these non-oily particles with an efficiency of 95%. As long as the product meets the N95 standard and has passed the NIOSH review in the United States, it can be called an "N95 type mask".

1. Different standards for use: N95 masks are produced in accordance with the standard grade 42CFR84 stipulated in the United States; The KN95 is produced in accordance with the standard grade GB2626-2006 stipulated by China.

2. Different functions: N95 is mainly used for respiratory protection; Whereas, KN95 is mainly used for dust prevention.

3. Different devices: N95 has two kinds of devices, one is with a breathing valve device, and the other is without a breathing valve device; The KN95 device is relatively simple, it only has one device, that is, there is a breathing valve device.

4. Different applicable populations: It should be noted that the applicable population of N95 is medical staff; The KN95 is suitable for workers who produce a lot of dust at work, such as sanitation workers, miners, etc.

The effect of N95 and KN95 masks is the same. KN95 mask is a professional dust mask that meets China's GB2626 standard, while N95 mask is a mask certified by NIOSH in the United States, and its standards are the same, both of which are for non-oily particles above the diameter with a filtration efficiency greater than or equal to 95%.

Features of N95 and KN95 masks:KN95 masks and N95 masks are actually just different names, they have the same protection level in product classification and filtration efficiency, and can be used with confidence, without caring about the difference in protective effect, during the epidemic taking into account the contagiousness of the virus and the actual situation of mask shortage, for the healthy general public, if there is no particularly high risk of exposure, you can choose medical surgical masks or general disposable masks.

That's fine, the KN95 mask and the N95 mask have the same antiviral effect.

KN95 and N95 are both production standards for masks, the N95 standard is an international standard, and KN95 is a standard formulated by China, no matter which standard it is, it has a good antiviral effect.

The formulation of this standard is mainly that after the tester wears the mask, the air particles inside the mask are reduced by more than 95% compared with the air particles outside the mask, which is called the N95 or KN95 standard. As long as you see both of these standard masks in the market, you can buy them, as long as you make sure that the masks are worn correctly and protect your face adequately, the antiviral effect can be achieved.

What is the difference between KN95 and N95 masks, in fact, the standards for mask production and testing are different, and the protection level of KN95 and N95 masks is comparable, but they follow the testing standards of different countries.

1. The standards are different: KN95 is the Chinese standard GB2626-2006, and N95 is the American NIOSH-42CFR Part 84.

2. The Chinese name is different: the Chinese name of KN95 is KN95 particulate matter protective mask, and the Chinese name of N95 is N95 medical protective mask.

3. Different use scenarios: KN95 is suitable for use in high-density public places and high-risk environments, while N95 is mostly used for medical staff.

The two are the same, there is no difference.

KN95 is one of the levels specified in the Chinese standard GB2626-2006, and N95 is one of the classes specified in the American standard 42CFR84. The technical requirements and test methods of these two levels are basically the same, and the filtration efficiency reaches 95% under the corresponding standards.

The N95 mask is actually a respirator, which is a respiratory protective device that is designed to fit the face more tightly than ordinary masks, and can filter particles in the air very effectively.

Among them, n stands not resistant to oil, which can be used to protect non-oily suspended particles; 95 means that the filtration efficiency is greater than or equal to 95%, indicating that after careful testing, this respirator can block at least 95 very small (micron) test particles.

In terms of design, if you rank according to the priority of the wearer's own protection ability (from high to low): N95 masks, surgical masks, ordinary medical masks, ordinary cotton masks. If worn correctly, the filtration capacity of N95 is better than that of ordinary masks and medical masks.

However, even if worn exactly as required, the risk of contracting illness or death cannot be 100% eliminated.

The protection of the KN95 and N95 is just as good.

The N95 mask is one of the nine types of particulate masks certified by NIOSH (National Institute for Occupational Safety and Health). "n"The meaning is non-oily particles; "95"This means that the filtration efficiency reaches 95% under the detection conditions specified in the NIOSH standard. As long as the product meets the N95 standard and passes the NIOSH review, it can be called an "N95 type mask".

This is the American standard and has the highest recognition in the world.

The domestic KN95 is actually the same detection method as N95. The latest dust mask standard has a clear classification of dust filtration efficiency levels, and the half mask has three filtration levels: N90 (protection efficiency 90%), N95 (protection efficiency 95%), and N100 (protection efficiency or above). Therefore, the dust mask standard of N100 is the safest.

What is the difference between N95 and KN95 masks?

The difference between mask N95 and KN95 is that the national standards are different, the N in mask N95 is the American standard mask, and the KN95 mask KN is the Chinese mask standard. The number after the letter represents the degree of protection of the mask, and the higher the number, the higher the level of protection. Therefore, they are almost the same, that is, N95 masks have strong requirements for breathability.

The KN95 mask follows the Chinese testing standard, and the N95 mask follows the American testing standard. The two masks are about the same. The key to wearing a mask is to fit the face tightly, that is, not to leak air. Please read the instructions carefully before wearing.

The difference between N95 and KN95 is that the production standards are different, one is a Chinese standard, the other is a foreign standard, and there is no difference in quality between the two, both are the same.

KN95 follows the Chinese national standard, N95 follows the American national standard, the protection level of the two is comparable in terms of protection, there is not much difference, both can be used for protection, both can prevent viruses.

These two standards are similar, but they are the mask standards of the United States and China. In fact, buying a KN95 mask can completely protect against the invasion of the virus, and in this summer, you only need to pay attention to choosing a cool, breathable KN95 mask, and the zeolite protective mask recommended by my friend is quite easy to use.

It's the same, but it's called differently.

The "N95" in NIOSH indicates a 95% efficiency for particulate matter down to the micron. In fact, the highest level of ASTM and FFP standards requires higher particulate filtration efficiency than NIOSH N95. For example, ASTM Level 3 requires a filtration efficiency of 98% for particles as small as microns.

Pu Weixin meets the highest standards of the United States, and the United States imports from Beijing.

The KN standard is a dust mask standard developed by China on the basis of the NIOSH standard in the United States. The protection efficiency is divided into 90 95 100, and the protection categories are divided into N and P categories. By comparison, the Chinese standard is consistent in the United States of KN95 and KN100.

KP100 standard is consistent.
