Patent ID: 8562708

Claim:
A three-dimensional filter comprising: a. a frame comprising: i. a wall forming a periphery that defines a space within the periphery wherein the periphery includes a pair of opposite end walls and a pair of opposite side walls, wherein each of the end walls is a single wall comprising a solid lower planar end wall portion and solid end wall peaks that protrude from and are inwardly slanted with respect to the lower planar portion, and open notches are defined between the end wall peaks and wherein each of the side walls is a single wall comprising a lower planar side wall portion and an upper side wall planar portion inwardly slanted with respect to the lower planar side wall portion; and ii. a skeletal structure occupying the space within the periphery wherein the skeletal structure has peak ribs extending between the solid end wall peaks of the opposite end walls and valley ribs and extending between the solid lower planar portion of the opposite end walls, wherein the peak ribs and the valley ribs form peaks and valleys in the skeletal structure with open ends, and wherein the solid end wall peaks and the solid lower planar portion are attached to the open ends and close the open ends of the skeletal structure; and b. a filter media connected to the skeletal structure and conforming to the peaks and valleys of the skeletal structure and terminating at the solid end wall peaks.
