Patent ID: 7585345

Claim:
A filter comprising: a first side including a plurality of entry openings; and a plurality of baffle members positioned to deflect air as the air enters the entry openings; wherein each of the plurality of baffle members extends toward the first side past a corresponding entry opening from the plurality of entry openings to form a channel through which the air travels; and wherein each of the plurality of baffle members extends past the corresponding entry opening so that each of the plurality of baffle members is positioned closer to the first side than the corresponding entry opening and so that the difference between a distance from each of the plurality of baffle members to the first side and a distance from the corresponding entry opening to the first side is at least the same as the depth of the channel; and wherein the air that passes through the filter is divided into a first air flow and a second air flow, the first air flow combining with an adjacent air flow to form a third air flow and the second air flow combining with an adjacent air flow to form a fourth air flow, the third air flow and the fourth air flow each being divided into two additional air flows before exiting the filter.
