The medical N95 mask has the same protection level as the ordinary N95 mask, and both have passed the N95 grade test. The difference between N95 mask and ordinary N95 mask;
1. Protective type: one is a medical mask and the other is an industrial dust mask. Of course, the corresponding certification standards are also different.
2. Scope of use: N95 medical protective mask is used in medical and health industries, such as epidemic prevention stations, hospitals, disease control centers, etc. N95 masks are used in industries, such as coal mines, petroleum processing, mines and other industrial and mining enterprises.
3. Usage: N95 medical protective mask can not only protect against viruses, but also filter fine dust; However, N95 dust mask can only effectively block dust, but not protect against viruses and germs.
4. Materials used: N95 masks are generally divided into three layers: outer layer, middle layer and inner layer. Although the diameter of the filter screen in the middle layer is the same, the materials used in the three layers are different.
What's the difference between n95 and kn95?
There is no obvious difference between N95 mask and KN95 mask, but there are some differences in manufacturing and testing.
N95 mask and KN95 mask have the same protection level, but they pursue different testing standards. N95 masks follow the testing standards of the United States, and KN95 masks follow the testing standards of China. Both of them have good protection efficiency for non-oily particles, such as sodium chloride particles used in the experiment, and the protection efficiency is above 95%.
