What's the difference between n95 dust mask and n95 mask?
Although the difference between N95 medical protective mask and N95 mask is only two words, laymen may not see it, but it is also a world of difference in use. Let's talk about the difference between the two in detail.
Similarities between N95 medical protective mask and N95 mask:
The protection level is the same, and they all passed the N95 level test, which is in line with the N95 approval of National Occupational Safety and Health Association (NIOSH). The diameter of the filter particles can be as small as 0.3 micron. In the test, particles with a diameter of 0.075 micron were separated, and the success rate was 95%. The diameter of coronary pneumonia (atypical pneumonia) is about 0. 1 to 0. 12 micron. Therefore, it can be used to prevent influenza in theory, so it can be considered as a standard protective mask when an epidemic occurs.
The difference between N95 medical protective mask and N95 mask;
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: N95 medical protective mask is used in medical and health industries, such as epidemic prevention stations, hospitals, 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 prevent diseases, but also filter fine particles of dust; However, N95 dust mask can only effectively block dust, but it can't protect germs well.
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.
There is no difference in the protection level between the two. The only difference is the occasion of use. Medical protective masks should be used as medical workers, and ordinary absorbent gauze masks should be used as special occasions in the daily life of ordinary citizens, such as seeing a doctor and visiting patients. Ordinary citizens also choose medical masks.
When choosing a mask, it depends on whether there is a trade name on the package, whether there is information about the manufacturer or supplier, and whether there is a mask certificate or instructions for use. Disposable masks should also have disposable labels, and reusable medical protective masks should also be marked with sterilization methods.
Generally speaking, ordinary gauze masks should indicate whether they are ordinary or sterile. The material used in the mask should be odorless and harmless to human body, especially the material in contact with human face should be non-irritating and allergic.
