Since the diameter of the pneumonia (SARS) virus is about 0.1 to 0.12 microns, wearing an N95 or KN95 mask is a viable preventive method.

In addition, medical surgical masks can also be used to prevent infectious diseases. Medical surgical masks can block 70% of bacteria, N95 masks can block 95% of bacteria, and the latter has a stronger blocking effect.

Paper masks, activated carbon masks, cotton masks, and sponge masks he limited effectiveness in preventing infection due to their tighter materials.

For the purpose of self-protection and reducing the risk of respiratory infections, the latter two masks (medical surgical masks and N95 masks) can be worn.

If you go to a generally open public place, do not he close contact with respiratory patients, wear a medical surgical mask, and no excessive protection is enough. However, if you come into contact with patients with suspected respiratory infections, you need to wear anti-biological N95 masks for effective protection.

But we soon discovered that these masks were basically out of stock and in the replenishment stage, which made us feel at a loss. Interested netizens found another Korean mask, the standard is KF94. See if this KF94 can meet everyone's needs.

As we all know, KN95 is the standard for protective masks in my country, which means that non-oily particles with a diameter of 0.3μm filter more than 95%. KF94 mask is a standard made in Korea. According to data from the official website of the Korean Food and Drug Administration (MFDS), the filtering rate of masks for particles with a diameter of 0.4 μm under this standard is above 94%. In other words, the KF94 standard mask can filter out at least 94% of particles with a diameter equal to 0.4μm. Therefore, KF94 is similar to KN95 and N95. It is a mask under the same protection level, but its protection capabilities are different.
