The FFP3 protective mask is manufactured with nanofibrous film as the core filter layer. And a four-layer structure of the mask is formed by the nanofibrous film with non-woven fabric, which is lighter and thinner than. The mask with at least 99% filtration efficiency effective against certain non-oil and oil based particles like dust, pollen, gases, odors,Oil fume, oil mist, asphalt smoke, coke oven smoke,and it can effectively separate PM2.5 fine particles and bacteria.Unique design with heightened nose piece and adjustable clip.Good balance between high efficiency of filtration and comfortable.
The nanofibrous film is a flexible and elastic microporous material with high porosity and uniform pore size distribution, which has the characteristics of water-proof and air permeability. So the filter is comfortable to wear, and can protect against particulate matter and limited liquid splashing. The nanofibrous film is a high-performance material, which is resistant to high temperature and corrosion with high toughness and strength. The biocompatibility of the film is great. the pore size in nanoscale of the nanofibrous film can directly block bacteria, viruses and dust as a physical barrier.
General isolation of the daily personnel contact areas such as offices, homes, schools, and public transportation facilities.
