Abstract: Aerosol particulate emission pollution is an obstacle to the improvement of atmospheric environmental quality in our country. As the emission control of aerosol particles，the filter filtration and dust removal technology has the obvious characteristics of high filtration efficiency，stable operation，various kinds and wide selection of fiber filtration media. It is evidence that fiber filtration technology has formed a variety of filtration materials，and has more complete theoretical support and related technical specifications. In this paper，the filtration theory，key parameters，development of filtration media，filtration process and filtration technology of aerosol particle fiber filtration were comprehensively expounded，the new technologies in this field were introduced，to provide references for the domain of aerosol particle filtration and dust removal.

Key words: aerosol particle, fiber filtration, cleaning, filtration theory, emission control of fine particulate matter
