1. Protective type: one is medical protective mask and the other is industrial dust mask. Of course, the corresponding certification standards are also different.
2. Scope of use: medical protective masks are used in medical and health industries, such as epidemic prevention stations, hospitals, disease control centers, etc. Dust masks are used in industries, such as coal mining, petroleum processing, mining and other industrial and mining enterprises.
3. Usage: The medical protective mask can not only protect the virus, but also filter the 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.
5. Liquid protection: Because N95 medical protective mask has the function of preventing liquid splash, the outer surface of the mask is covered with a green hydrophobic protective layer, which is mainly used to prevent slight liquid or blood splash from penetrating. N95 mask does not have this hydrophobic protective layer.
