What is the standard of KF94 mask?

KF94 is a Korean standard, and the filtration rate of the mask for particles with an average diameter of 0.4μm is above 94%. Different from the American standard of N95, the standard of KF94 mask is based on the data of South Korea and refers to the American Food and Drug Administration (MFDS) of South Korea.

The occurrence of COVID-19 has taught us a lot about different types of masks, and KF94 mask is one of them. Maybe many people have never heard of this mask before, so does this mask really meet the standard? Let's talk about the standard of KF94 mask first.

0 1 KF94 is a Korean standard, and the filtration rate of the mask for particles with an average diameter of 0.4μm is more than 94%. Different from the American standard of N95, the standard of KF94 mask is based on the data of South Korea and refers to the American Food and Drug Administration (MFDS) of South Korea.

02 KF94 mask can filter out at least 94% of particles with a diameter of 0.4μm, and both oily and non-oily particles can reach the same level. Splash resistance and bacterial filtration are not required. N95 mask can filter out at least 95% of particles with a diameter of 0.3μm, which is limited to non-oily particles. Splash resistance and bacterial filtration ability are not required.

Compared with N95, the filtering effect of N95 is better (filtering diameter and filtering speed are better than those of KF94), but KF94 has higher requirements for filtering oily particles than N95. The other two non-medical masks have no requirements for bacterial filtration efficiency and splash resistance, so the effect is not as good as that of special medical series.
