Medical protective masks are composed of a mask body and a tension band. The mask body is divided into three layers: inner, middle, and outer. The inner layer is ordinary sanitary gauze or non-woven fabric, and the middle layer is single-layer or multi-layer ultra-fine polypropylene fiber meltblown. Material layer, the outer layer is non-woven fabric or ultra-thin polypropylene meltblown material layer. This high-efficiency medical protective mask has strong hydrophobic and air permeability, has a significant filtering effect on tiny virus-carrying aerosols or harmful dust, and has a good overall filtering effect.
Medical protective masks have a good fit with the wearer’s face, can filter particles in the air, block pollutants such as droplets, blood, body fluids, and secretions, and have a filtration efficiency of more than 95% for non-oily particles. Personal protective equipment commonly used in response to airborne diseases.
