Abstract: A filter element including a first filter media pack with an inlet face and an outlet face and a second filter media pack with an inlet face and an outlet face. The second filter media pack is formed separately from the first filter media pack and is coupled to the first filter media pack such that the respective inlet faces and outlet faces of the first and second media packs do not overlap. The first filter media pack and the second filter media pack each include a corresponding filter media pack characteristic, and the filter media pack characteristic of the first filter media pack is different from the corresponding filter media pack characteristic of the second filter media pack. Exemplary filter media pack characteristics include the length, width, height, shape, media density, layer spacing, pleat bend angle, pleat density, and material composition of the first and second filter media packs.
