The KF94 mask is a standard made by South Korea. According to the data on the official website of the Korean Food and Drug Administration (MFDS), the mask under this standard has a filtration rate of more than 94% for particles with a diameter of 0.4μm. Therefore, the KF94 standard mask can filter out at least 94% of the particles with a diameter equal to 0.4μm. Therefore, KF94 is similar to KN95 and N95. They are all masks under the same protection level, but they differ in their protection capabilities.
This standard can effectively block the common vector of viruses: droplets. The diameter of droplets is generally between 1~4μm. The filtering effect of the KF94 mask can prevent droplets from directly contacting the human respiratory tract and prevent virus invasion.
However, because KF94 is not aimed at medical standards, there is no relevant standard for bacterial filtration rate in the production process. In addition, the outer material is the same as the non-medical KN95 and N95 masks. The splash resistance is not as good as that of medical ones. Once it is contaminated with droplets, if the mask is not replaced for a long time, there will still be risks.
Therefore, KF94 can take on the role of personal protection when going out, but its effect is slightly inferior to KN95 level protective masks.
