The capacity and efficiency of a filter element having pleated filter media is increased by utilizing a baffle across the upstream front area of the filter media. The baffle is preferably a web of material that is adhered to the peaks of the filter media. Preferably, the baffle is laterally offset and has a width which is in the range of 20-75% of the width of the filter media. Utilizing the baffle does not increase restriction to an unacceptable range.
