UNISEX Flat Disposable KN95 Face Mask With Earlock 5 Layer Melt Blown Non Woven

Description - 50 pcs white The barrier efficiency is higher. The main reason is that the fiber diameter of the material used is smaller than that of traditional materials (the fiber diameter of non-woven materials used in traditional masks is more than 1000 nanometers), which can more effectively block PM2.5 in the air (aerodynamic equivalent diameter is 2500 nanometers or less Particles), and effectively reduce the concentration of bacteria and viruses in the air The service life is longer. The reason is that it uses physical principles to isolate air pollutants and is more durable. (The non-woven fabric used in traditional masks has a large fiber diameter and needs to rely on electrostatic adsorption of particulate matter. Static electricity is affected by temperature and humidity in the environment in a short time. Failure, so it can only be used once) Breathing more easily and freely when worn. This is mainly due to the better air permeability and moisture resistance of the nano film. Film masks have both excellent breathability and protective performance, reflecting the mainstream development direction of masks in the future.
