It has good filtering effect and slightly poor air permeability. The latest variety is non-woven fabrics on the surface and back, and filter paper in the middle, which makes the filtering effect of non-woven masks a step further. The dust blocking efficiency of non-woven masks is based on its blocking efficiency for fine dust, especially for respirable dust below 5 microns.
