Abstract
A dual pleated air filter according to the present disclosure may include two or more generally parallel, pleated filter elements layered perpendicular to the influent air stream and having the pleats of adjacent filter elements oriented orthogonally. Within each pleated filter element are an influent mesh layer and a corresponding effluent mesh layer for supporting filter media and one or more layers of filter media are located between the influent and the effluent mesh layers. The relative orientation of pleats of adjacent elements may range from parallel to perpendicular.
