•The KF94 mask is a standard produced in South Korea. According to the data on the official website of the Korea Food and Drug Administration (MFDS), the mask under this standard has a filtration rate of more than 94% for particles with a diameter of 0.4 μm.

•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. They are all masks under the same protection level, but the protection ability is different.

•This standard can effectively block the common carrier of the virus: droplets.

•The diameter of the droplets is generally between 1 and 4 μm. The filtering effect of the KF94 mask can prevent the droplets from directly contacting the human respiratory tract to the greatest extent and prevent the invasion of viruses.
