AERODYNAMIC FILTER ABSTRACT OF THE DISCLOSURE The filter of the present invention continually provides the passenger compartment of a vehicle with a supply of purified air, even in the most severe environmental conditions. The filter comprises an inlet surface, an outlet surface, walls which define a plurality of passages which extend from the inlet surface to the outlet surface, and a filtration means for removing the impurities from the fluid. The filter preferably can be subdivided into a plurality of layers, including an inlet layer, an intermediate layer, an outlet layer. Each layer includes a plurality of cells, the cells having walls with a generally curvilinear shape. A plurality of the passages are preferably in fluid communication with a plurality of other passages. Surface filtration is used to remove the impurities from the fluid flowing through the passages. The impurities are retained within the filtration means which are disposed on the walls, as the fluid flows through the passages essentially unrestricted even when the removing means is saturated with impurities.
