1. An air filter, comprising: a filter media;a first support structure having a center portion and sidewalls positioned on opposite sides of the center portion, the center portion of the first support structure attached to a first side of the filter media; anda frame having a plurality of sections,
1. An air filter, comprising: a filter media;a first support structure having a center portion and sidewalls positioned on opposite sides of the center portion, the center portion of the first support structure attached to a first side of the filter media; anda frame having a plurality of sections, each of the sections having a center portion and sidewalls positioned on opposite sides of the center portion, a first frame section attached to the first support structure by connecting the sidewalls of the first frame section to the sidewalls of the first support structure to form a hollow channel between the first support structure center portion and the first frame section center portion, and between the sidewalls of the first support structure. 2. The air filter of claim 1, further comprising: a second support structure having a center portion and sidewalls positioned on opposite sides of the center portion, the center portion of the second support structure attached to a second side of the filter media; anda second section of the frame attached to the second support structure by connecting the sidewalls of second frame section to the sidewalls of the second support structure to form a hollow channel between the second support structure center portion, the second frame section center portion, and the sidewalls. 3. The air filter of claim 2, wherein the second side of the filter media is located on a side opposite the first side of the air filter media. 4. The air filter of claim 1, further comprising: at least one reinforcing strip attached to a face of the air filter media, each of the at least one reinforcing strips attached to one or more frame section sidewalls. 5. The air filter of claim 1, wherein the air filter media is pleated, and wherein the first side of the air filter media is a pleated side of the air filter media. 6. The air filter of claim 1, wherein the air filter media is pleated, and wherein at least one reinforcing strip is attached to peaks formed by the pleating of the air filter media. 7. The air filter of claim 1, wherein the first support structure sidewalls extend from the first support structure center portion in a direction generally away from the air filter media. 8. The air filter of claim 1, wherein a first sidewall of the first support structure extends from the first support structure center portion in a direction generally away from the filter media, and wherein a second sidewall of the first support structure extends from the first support structure center portion in a direction generally toward the air filter media. 9. The air filter of claim 1, wherein the first support structure sidewalls and the first support structure center portion are formed from a single piece of material, and wherein the first support structure sidewalls are formed by bending the edges of the material out of the plane of the first support structure center portion. 10. The air filter of claim 1, wherein the first support structure sidewalls and the first support structure center portion are formed from a single piece of material, and wherein each of the first support structure sidewalls are formed by folding the edges of the material away from the first support structure center portion along a crease. 11. The air filter of claim 1, wherein the first support structure sidewalls and the first support structure center portion are formed from a single piece of material, and wherein each of the first support structure sidewalls are formed by folding the edges of the material along two or more creases. 12. The air filter of claim 2, wherein the first support structure, the second support structure, a third side of the filter media, and a fourth side of the filter media are attached to sections of the frame so that air is unable to pass between the filter media and the frame. 13. A method of manufacturing an air filter, comprising: providing an air filter section comprising a filter media and support structures attached to opposite, pleated sides of the filter media, the support structures each having a center portion and sidewalls positioned on opposite sides of the center portion;providing a frame assembly having a plurality of segments, each of the segments having a center portion and sidewalls positioned on opposite sides of the center portion;positioning the air filter section so that a first side of the air filter section is located above a first frame segment;moving the air filter section into a framing form so that the first side of the air filter section contacts the first frame segment;moving a second frame segment into contact with a second side of the air filter section and moving a third frame segment into contact with a third side of the air filter section, the second and third frame segments attached to opposite ends of the first frame segment, the movement of the second and third frame segments caused by the movement of the air filter section into the framing form;moving a fourth frame segment into contact with a fourth side of the air filter section; andattaching sidewalls of the air filter section support structures to sidewalls of corresponding frame segments to form a hollow channel between the support structure and the corresponding frame segment along the pleated sides of the filter media. 14. The method of claim 13, wherein the pleated filter media has a first face and a second face, and wherein at least one strut is attached to peaks on the first face of the pleated filter media, and at least one strut is attached to peaks on the second face of the pleated filter media. 15. The method of claim 13, wherein the frame assembly has a tab section attached to a first end of the frame assembly; and the method further comprising: attaching the tab section to a second end of the frame assembly. 16. The method of claim 15, further comprising: positioning the tab section between a frame segment and a side of the air filter section. 17. A method of attaching a frame to an air filter, comprising: providing a filter slug comprising a filter media and reinforcing structures attached to opposite sides of the filter media, the support structures each having a center portion and sidewalls positioned on opposite sides of the center portion;providing an unassembled frame having a plurality of segments, each of the segments having a center portion and sidewalls positioned on opposite sides of the center portion;positioning a first frame segment between a first side of the filter slug and a frame form;moving the filter slug into contact with the first frame segment and into the framing form;rotating second and third frame segments into contact with second and third sides of the frame slug, the rotation of the frame segments caused by the movement of the filter slug and frame into the framing form;rotating a fourth frame segment into contact with a fourth side of the filter slug; andpermanently bonding the sidewalls of the filter slug reinforcing structures to the sidewalls of corresponding frame segments to form a hollow channel between the reinforcing structure and the corresponding frame segment. 18. The method of claim 17, wherein the filter media is pleated and has a first face and a second face, and wherein at least one support strut is attached to peaks on the first face of the pleated filter media, and at least one support strut is attached to peaks on the second face of the pleated filter media.
