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.
Therefore, KF94 can take on the role of personal protection when going out, but its effect is slightly inferior to KN95 level protective masks.
KF94 is the protection level of Korean protective masks, that is, the filtration rate of particles with a diameter of 0.4μm is greater than 94%. As a personal protective equipment to prevent new infections, KF94 masks are slightly inferior to KN95 or N95 level protective masks. But in today's shortage of materials, if there is no better choice, KF94 can play an effective protective role when individuals go out.
In fact, you don't necessarily need kn95 masks, because n95 masks can filter at least 95% of dust, viruses, smoke and other tiny particles. This mask is similar to a medical surgical mask and consists of three parts: a surface moisture-proof layer, an intermediate filter adsorption layer and an inner skin layer. The main material is polypropylene melt blown cloth.
Take personal protection and actively wear a mask. Wear disposable medical masks when going out in public places, taking public transportation, and indoor activities; medical surgical masks or KN95 masks should be worn when going out for medical treatment.
The State Food and Drug Administration stated on the 7th that with the stable supply of masks in South Korea, the mask purchase restriction system will officially end on the 12th of this month and then be transferred to the market supply system. Therefore, consumers will be able to purchase Korean standard KF94 masks from pharmacies, supermarkets, and the Internet.
Emphasize: You must wear a mask when you go out!
