These two types are special models for medical staff, and the protection requirements are much higher than the anti-infection masks used by ordinary people. All masks marked as N95 meet a unified standard: they can block 95% of non-oily particles with a diameter of 0.3 microns or more. Whether it is dust or smog, as long as it is N95, it is useful for ordinary people. In addition, the protective effects of KN95 masks and surgical masks are similar to N95 masksIn order to meet the needs of different masks, there are many kinds of nose bridge strips: aluminum nose strips for medical surgical masks and KN95 masks; single-core nose bridges, double-core nose bridges, and all-plastic nose bridges for disposable masks.
Most authentic Korean kf94 masks are individually packaged. On a certain platform, you can see the inferior kf94 masks with a unit price of 26.8/piece, a pack of 10 packs, which looks like a thin layer, a bit similar to ordinary disposable ones in China. This one is more likely to be fake.
Generally speaking, Korean kf94 masks are certified and approved by the Korean Food and Drug Administration, and most of them are individually packaged with a thickness of 4-5 layers. You basically don't need to consider the kf94 in the transparent bag. It is more likely to be fake.
Specific and detailed separation methods.
1. First of all, make sure that some masks called (anti-epidemic) and kf94 on the package are genuine kf94 masks.
2. Check if there is certification and registration from the Korean Food and Drug Administration on the packaging. There are pictures below.
3. Whether there is a Korean website on the product packaging to check the authenticity, you can log in to check.
4. Generally, the outer packaging is not too bad and the value is quite high.
Although this kind of mask has good filterability, it cannot filter completely. Because haze not only contains non-oily particles, such as dust, acid mist, coal dust, cement dust, microorganisms, etc.; it also contains oily particles, such as oil fume, oil mist, asphalt fume, coke oven fume, diesel engine exhaust, etc. Medical protective masks cannot completely filter out oily particles and gaseous chemicals. It should be reminded that medical protective masks are usually used in medical environments and are not suitable for ordinary people to wear in their daily lives. For example, masks are usually used for occupational respiratory protection to block some microbial particles, but due to their thick texture, they are usually uncomfortable to wear.
The ordinary masks and disposable non-woven masks currently on the market may he a certain barrier effect on ordinary dust and large particles, but they are not enough to protect against haze, bacteria, viruses and other microbial particles. It is recommended to choose a mask marked with KN95 (low efficiency mask with 95% efficiency in filtering non-oily particles under the test conditions specified by the standard) and above. The KN95 mask produced by our company has five layers of protection and a built-in bridge of the nose. In addition, when consumers choose masks, in addition to their protective functions, they should also consider factors such as the user's face shape and comfort level to ensure effective protection.
