The pore size of the clean room FFU filter membrane is small and the distribution is concentrated, which can better prevent fine dust from entering the filter material, just like a first layer of artificial dust, achieving surface filtration (the accumulated dust can be easily removed by mechanical vibration or wiping) dust), the dust removal efficiency reaches 99.9%~99.999%, and even has high dust removal efficiency for fine particles of PM2.5~PM10, which can meet the filtration efficiency level requirements of sub-efficient, high-efficiency, and ultra-high-efficiency air filters.
