“KF” stands for Korean Filter. 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.
