But everyone soon discovered that these masks are basically in the stage of being out of stock and replenishment, leing everyone at a loss for a while. Interested netizens he discovered a mask from South Korea, the standard is KF94, let's see if this KF94 can meet your needs.

New forite online, KF94 mask

Everyone knows that KN95 is our country's standard for protective masks, which means that non-oily particles with a diameter of 0.3μm filter more than 95%. The KF94 mask is a standard developed 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. In other words, KF94 standard masks 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.

Can KF94 masks prevent viruses?

Although this data is not very effective for directly filtering viruses, after all, the diameter of the disease is only about 0.1μm, but it can effectively block the common virus carrier: droplets. The diameter of the droplets is generally between 1 and 4μm. The filtering effect of the KF94 mask can prevent the 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. Its 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.
