A structure and method including a filter assembly, wherein the structure can be an ink jet printhead including the filter assembly. The filter assembly can include a first filter layer having a plurality of pores therein, wherein the pores have a first pitch, and a second filter layer having a plurality of pores therein, wherein the pores in the second filter layer have a second pitch which is different than the first pitch. The structure can include a fluid path through the filter assembly. An area of overlap of the pores in the first filter layer with the pores in the second filter layer, in a vertical direction perpendicular to a plane of the filter assembly, can include a periodicity.
