Description

From the original cotton and cotton multi-layer filter masks to the currently widely used chemical fiber non-woven fabrics and glue-sprayed cotton masks, various filter materials are used to achieve filter protection. The protective respirator for military use is basically filtered and adsorbed by activated carbon. However, these technologies generally have low filtration efficiency, high resistance, and cannot be used repeatedly and continuously.
