With the spread of popular science information on the online epidemic, everyone is very familiar with personal protection for 2019- prevention. Everyone knows that masks are the best protective measure. In early February, medical surgical masks, N90, KN95/N95 level protective masks on the Chinese market were very difficult to buy.Therefore, many friends discovered the KF94 mask made in Korea, which quickly became a hot-selling product.

We are very familiar with N95 masks and KN95 masks, so what is this KF94?

First of all, KF94 is a Korean standard, which means that the filtration rate of the mask for particles with an average diameter of 0.4μm is greater than 94%. The source of this data is the Korean Video Drug Administration. (MFDS)

Secondly, in terms of protection ability, N95 level filter particles are better. However, compared with ordinary medical care masks, N95 and KF94 masks have better protection performance, and they can both play a certain personal protection role for everyone in daily travel.

At present, the period when it is difficult to buy masks has passed, and we can now buy products from regular manufacturers at a more favorable price. For example, the "KIEYYUEL" brand mainly deals in ten types of anti-epidemic products: disposable masks, N95/KN95 masks, disposable gloves (including PVC gloves, nitrile gloves, latex gloves, etc.), protective clothing, body bags, and Infrared thermometer and so on. Among them, this KN94 mask can also be bought on the official website.
