Zusammenfassung:	The present disclosure is directed to a filtering element. The filtering element may comprise at least one channel defined by at least one wall. The at least one wall extends longitudinally from a first end of the channel to a second end of the channel, the at least one channel having an unobstructed first end and an unobstructed second end. The filtering element further includes at least one partial barrier configured to reduce a path of a flow of exhaust through the at least one channel, the at least one partial barrier being positioned within the at least one channel so as to redirect a portion of the exhaust flow within the channel. The at least one channel includes a selective catalytic reduction catalyst on at least a portion of one of a surface of the at least one partial barrier or a surface of the at least one wall.
