1, not afraid of water. Generally, ordinary medical masks are afraid of water, so it will produce water vapor after wearing for a period of time. This water vapor will come in and out with the water vapor we breathe, the static electricity will be neutralized, and the mask will lose its protective effect. Graphene masks will not have such problems. First of all, graphene is a three-dimensional carbon structure with large attachment surface area, which can play a good adsorption role. Moreover, because the main component carbon is very stable and dense, slightly larger substances cannot pass through.

2. The filtering effect is the best. Ordinary medical masks and 3MN95 masks (mask concept) can prevent the intrusion of particles. For example, in foggy days, N95 can help filter, but what about toxic gases? Toxic gas is much smaller than particles because it is air. Graphene masks can filter the above two kinds of air that masks can't, thanks to the unique structure and atomic arrangement of graphene. The contact surface with the air is very large, and the air needs to run around the graphene structure many times before it can come out.

3, the longest use time, if the graphene mask has such a good use effect, is it not durable? From the data point of view, graphene masks are not only effective, but also have the longest single use time. A graphene mask can be used for about a month. The point is that this mask doesn't need disinfection. Many people will use alcohol, microwave oven or even boiling water to disinfect the used masks, which is not allowed and will destroy the masks and graphene. The original filter structure does not have this problem, and the mask does not need disinfection.
