A particulate filter may comprise an inlet end, an outlet end, and a plurality of channels disposed and configured to flow fluid from the inlet end to the outlet end, wherein the channels are defined by porous walls configured to trap particulate matter. The porous walls may have a cell density less than about 200 cpsi, a wall thickness of less than about 14 mils, a median pore size that ranges from about 13 micrometers to about 20 micrometers, a total porosity greater than about 45%, and a pore size distribution such that pores less than 10 micrometers contribute less than about 10% porosity.
