It consists of three layer material, the inner is non-woven fabric, the middle for superfine melt-blown polypropylene fibre material layer, outer layer of non-woven fabric or ultrathin polypropylene melt-blown materials; The tiny virus aerosol or harmful dust filtering effect significantly, oily particles blocking, filtering efficiency of air ≧ 95%. Although the filterability of the mask is very good, but it cannot be completely filtering. Because, fog not only contains the oily particles, such as dust, acid mist, dust and cement dust and microorganism; Also contain oily particles, such as, coke oven smoke lampblack, oil mist, asphalt smoke and diesel exhaust, etc. To oily particulate and gaseous chemical, medical respirator can filter out completely.
