A filter element for filtering a particle-containing paint composition or a particle loading slurry composition which is a precursor to a particle-containing paint composition is provided. The filtration element comprises at least one filtration layer formed from woven polymer fibers and having substantially uniform pores and two spacer layers. The spacer layers have raised projections to create a space between adjacent spacer layers having contacting projections. The filtration element has a pleated or spirally wound configuration.

[ What is claimed is:] [1.] A filtration element for filtering a particle-containing paint composition or a particle loading slurry composition to remove particles of a predetermined size and larger comprising:at least one woven polymer filter layer having substantially uniform sized ports of about said predetermined size and of a size between about 10 microns and about 105 microns,opposing surfaces of said at least one filter layer being in contact with a spacer layer having second pores therethrough, said second pores being larger than said substantially uniform sized pores,each of said spacer layers having at least one surface with raised projections,each of said spacer layers and said at least one filter layer being arranged to assure that an entire unblocked surface of said at least one filter layer is contacted with unfiltered paint composition or unfiltered slurry composition,and means for introducing said unfiltered paint composition or said unfiltered slurry composition into said filtration element and means for removing filtered paint composition or filtered slurry composition from said filtration element.
