Abstract
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.
