Can prevent "droplets". It is not very effective for directly filtering viruses, because the diameter is only about 0.1μm, but it can effectively block the common carrier of viruses: droplets.

The filtering effect of the KF94 mask can prevent the droplets from directly contacting the human respiratory tract and prevent virus invasion.

It is not a medical standard and should be replaced in time. Since it is not used in a medical environment, there is no relevant indicator of bacterial filtration rate in the production process. In addition, its outer material is the same as non-medical KN95 and N95 masks, and its splash resistance is not as good as medical masks. Once contaminated by droplets, there is still a risk if the mask is not replaced for a long time. —-It can be understood that it can be used occasionally when going out; for long-term wear, it is recommended to replace it in time after the replacement time.If there is no better choice, KF94 can play an effective protective role when individuals go out.

Although KF94 masks can be used, you should pay attention to whether the so-called "KF94" masks bought in China are genuine, especially those that claim to be imported. (If you buy it at a local store in Korea, it will be safer than buying in China, because South Korea will Supervise the quality of products sold locally). However, if you buy in China, it is recommended not to buy from private channels, but from formal channels (such as the one above, Wumart), because it is very likely that the domestic regulatory authorities cannot control the "private imported" masks, and the quality cannot be guaranteed. The biggest fear is that the masks you buy may be produced in underground factories. This is too common in the cosmetics field, right? Buying fake cosmetics is much more risky than buying fake cosmetics!
