Can KF94 masks offer protection against COVID-19?
May 19, 2021

The KF94 face mask is produced by Korea standards. According to the data on the official website of the Korean Food and Drug Administration (MFDS), this standard mask has a filtration rate of more than 94% for particles with a diameter of 0.4μm. In other words, the KF94 standard mask can filter out at least 94% of particles with a diameter equal to 0.4μm.

Although the data shows that is not very effective for directly filtering COVID-19 viruses, after all, the diameter of coronavirus is only about 0.1μm, but it can effectively block the common carrier of viruses: droplets. The diameter of the droplets is generally between 1~4μm. The filtering effect of the KF94 face mask can prevent the droplets from directly contacting the human respiratory tract and prevent the invasion of viruses.

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.

KF94 face masks is the protection level of Korean, that is, the filtration rate of particles with a diameter of 0.4μm is greater than 94%. in today's shortage of materials, if there is no better choice, KF94 can play an effective role in protection when individuals are out.
