Design effort focuses on extending filter’s service life. The inner pre-filter layer is coarser than the final filter layer to form graded pore depth structure. Coarse contaminant particles are trapped and retained by the pre-filter layer in order to protect and prolong the service life of the final layer. Both the pre-filter layer and the final filter layer are not singed so that the entirety of micro pore openings are preserved as it is. Such formulation is effective in slowing down the premature formation of filter cakes, There by successfully extending filter’s service life. A layer of spunbound cover is used to prevent fiber migration. Lab tests show
that the average service life is 85% to 110% longer than standard PP and PE bags, depending on application conditions..
