1. A refrigeration display case for refrigerating and displaying perishable goods, the refrigeration display case comprising: a base member for placing proximate a support surface;a back wall coupled to and substantially perpendicular to the base member and extending substantially vertically in an assembled position;a canopy assembly coupled to and substantially perpendicular to the back wall, the canopy assembly having a front end, and having a short-dimension width and a long-dimension length;an air deflector coupled to the canopy assembly proximate the front end;wherein the base member, back wall, and canopy assembly form a display area;wherein the air deflector comprises:a first member that is substantially vertical in the assembled position having a first end and a second end and having a first surface and an opposing second surface,a locating feature extending from the second surface of the first member,a deflecting surface member extending from the second surface of the first member and having a distal end with a securing flange for securing to a portion of the canopy assembly,wherein the deflecting surface member partitions the first member and defines a first portion and a second portion of the first member,wherein the second portion of the first member has a distal end that comprises a first filter-support shelf member sized and configured to receive a first end of a filter member, anda flexible hinge formed on the second portion of the first member to allow at least movement of a moveable portion of the second portion; anda second filter-support shelf member coupled to a portion of the canopy assembly and spaced from the first filter-support shelf member, wherein the second filter-support shelf member is sized and configured to receive a second end of a filter member. 2. The refrigeration display case of claim 1, further comprising a filter member having a rectangular cross section and removably held between the first filter-support shelf member and the second filter-support shelf member. 3. The refrigeration display case of claim 1, wherein the first member has a length, L1, and the locating feature extends from a location on the second surface that is between 5 percent and 45 percent of L1 from the first end of the first member. 4. The refrigeration display case of claim 1, wherein the first member has a length, L1, and wherein the deflecting surface member is coupled to the first member between 50 percent and 90 percent of the length of the first member from the first end. 5. The refrigeration display case of claim 1, wherein the deflecting surface member has a length L2 and extends from the first member substantially perpendicularly for between 40 percent and 60 percent L2 before curving and then ending with the securing flange that is substantially flat. 6. The refrigeration display case of claim 5, wherein the securing flange has a first fastener aperture therethrough for receiving a fastener. 7. The refrigeration display case of claim 1, wherein the first member has a second fastener aperture therethrough proximate the first end for receiving a fastener. 8. The refrigeration display case of claim 1, wherein the second filter-support shelf member comprises a longitudinal member having a shelf tab portion for interfacing with a bottom side of a filter member and a side support surface that extends substantially perpendicularly to the shelf tab portion for interfacing with a side of the filter member, and having a canopy surface portion that extends substantially parallel to the side support surface for coupling to the canopy assembly. 9. The refrigeration display case of claim 1, wherein the flexible hinge formed on the second portion of the first member is configured to allow movement of the moveable portion of the second portion at least between 5 and 40 degrees relative to first portion of the first member. 10. The refrigeration display case of claim 1, wherein the first member is an integrated member formed by injection molding or extrusion and then stamping or machining to reduce or compress material in a portion to form the flexible hinge. 11. The refrigeration display case of claim 1, wherein the deflector surface member has a first side and a second side, and wherein in the assembled positioned, the deflector surface member is configured to have air delivered from the back wall impact the second side and be directed to a top surface of the filter member. 12. An air deflector for use in a refrigerated display case at a location proximate a first end of a canopy assembly, the air deflector comprising: a first member that is substantially vertical in an assembled position having a first end and a second end and having a first surface and an opposing second surface,a locating feature extending from the second surface of the first member,a deflecting surface member extending from the second surface of the first member and having a distal end with a securing flange for securing to a portion of the canopy assembly,wherein the deflecting surface member partitions the first member and defines a first portion and a second portion of the first member,wherein the second portion of the first member has a distal end that comprises a first filter-support shelf member sized and configured to receive a first end of a filter member, anda flexible hinge formed on the second portion of the first member to allow at least movement of a moveable portion of the second portion. 13. The air deflector of claim 12, wherein the first member has a length, L1, and the locating feature extends from the second surface between 5 percent and 45 percent of L1 from the first end of the first member. 14. The air deflector of claim 12, wherein the first member has a length, L1, and wherein the deflecting surface member is coupled to the first member between 5 percent and 65 percent of the length of the first member from the first end. 15. The air deflector of claim 12, wherein the deflecting surface member has a length L2 and extends from the first member substantially perpendicularly for between 40 percent and 60 percent L2 before curving upwardly for an orientation in an assembled position and then ending with the securing flange that is substantially flat. 16. The air deflector of claim 12, wherein the deflecting surface member has a length L2 and extends from the first member substantially perpendicularly for between 40 percent and 60 percent L2 before curving upwardly for an orientation in an assembled position and then ending with the securing flange that is substantially flat; wherein the deflecting surface member comprises a first portion and a second portion with a curvature angle formed therebetween, and wherein the curvature angle is between 100 and 170 degrees. 17. The air deflector of claim 12, wherein the flexible hinge flexes between 5 and 45 degrees. 18.
