The presence of such a filter indicates the high quality of the protective masks. The filter is made of 5 layers of microfiber, making it a high-efficiency barrier for bacteria passing through the mask. The multi-layer structure is designed for a reason. The outside layers capture bacteria as you inhale, the middle layer is used for even finer filtration and the layer touching your skin is used for functional finishes such antibacterial and antifungal.
The filter material meets the safety requirements of the USFDA (US Food and Drug Administration). The mask protects you from breathing in harmful PM 0.3 and the air gets passed through the filters easily.
Filter replacement is not a hard process at all. In order to put the fresh filter in correctly make the marks R and L, written on the inner side of the filter, meet with the identical marks indicated on the mask. Just slide the filter half into the grooves located on the inner part of the mask.
Numerous studies proved an ergonomic design of the Xiaomi MiJia Airwear Anti-Fog And Haze Mask. The filter offers a 360-siliconeseal covering the area from the bridge of your nose to the chin and stays sealed to your face while you breathe and speak.
