Characteristic Parameters Affecting the Filtration Performance in Fibrous Porous Media

Fibrous porous media plays an important role in aerosol or small particle filtration. The filtration of fibrous porous media is a composite process, of which the filtration performance is affected by many parameters and is quite difficult to be predicted precisely. In this paper the parameters affecting the filtration performance are re-examined. Especially, the influences of fiber sizes and the porosity of the porous media to the filtration efficiency are analyzed further.
