The invention claimed is: 1. A canister assembly comprising: a canister body; an inner wick formed from blotter paper positioned within the canister body and configured to define an air passage; and an outer wick formed from felt, at least a portion of the outer wick being positioned between the inner wick and the canister body, the inner wick and the outer wick being oriented to enable a transfer of fragrance material to the inner wick from the outer wick, the fragrance material including fragrance molecules, the inner wick being configured to enable a transfer of some of the fragrance molecules into air within the air passage. 2. The canister assembly of claim 1 wherein the outer wick has a greater tendency to transfer the fragrance material than the inner wick. 3. The canister assembly of claim 1 wherein the inner wick and the outer wick form substantially concentric cylinders. 4. The canister assembly of claim 1 wherein the outer wick has an outer surface, the canister assembly further comprising: a wrapper, at least a portion of the wrapper being positioned between the outer wick and the canister body, wherein the wrapper encases at least a portion of the outer surface of the outer wick. 5. The canister assembly of claim 4 further comprising: a lip, wherein the lip interacts with the wrapper to form a seal between the wrapper and an inner surface of the inner wick. 6. The canister assembly of claim 1 further comprising: a lip for collecting excess fragrance material. 7. The canister assembly of claim 1 wherein the fragrance material comprises fragrance oil. 8. The canister assembly of claim 1 wherein: the inner wick and the outer wick form an integrated wick, the inner wick comprises an inner portion of the integrated wick, the outer wick comprises an outer portion of the integrated wick, and the outer portion of the integrated wick is more porous than the inner portion of the integrated wick. 9. The canister assembly of claim 1 wherein felt of the outer wick has a denier within a range of 3-6. 10. The canister assembly of claim 1 wherein: the outer wick has an inner surface positioned adjacent to the inner wick and an outer surface positioned opposite the inner surface; and fibers of the felt of the outer wick are arranged to provide a grain within the outer wick that runs between the outer surface and the inner surface of the outer wick. 11. A canister assembly comprising: a canister body; an inner wick positioned within the canister body and configured to define an air passage; and an outer wick having an outer surface, at least a portion of the outer wick being positioned between the inner wick and the canister body, the inner wick and the outer wick being oriented to enable a transfer of fragrance material to the inner wick from the outer wick, the fragrance material including fragrance molecules, the inner wick being configured to enable a transfer of some of the fragrance molecules into air within the air passage; a wrapper, at least a portion of the wrapper being positioned between the outer wick and the canister body, wherein the wrapper encases at least a portion of the outer surface of the outer wick; and a lip, wherein the lip interacts with the wrapper to form a seal between the wrapper and an inner surface of the inner wick. 12. A canister assembly comprising: a canister body; an inner wick positioned within the canister body and configured to define an air passage; an outer wick, at least a portion of the outer wick being positioned between the inner wick and the canister body, the inner wick and the outer wick being oriented to enable a transfer of fragrance material to the inner wick from the outer wick, the fragrance material including fragrance molecules, the inner wick being configured to enable a transfer of some of the fragrance molecules into air within the air passage; and a lip for collecting excess fragrance material. 13. A canister assembly comprising: a canister body; an inner wick formed from blotter paper positioned within the canister body and configured to define an air passage; and an outer wick formed from a woven fibrous material that differs from the inner wick, at least a portion of the outer wick being positioned between the inner wick and the canister body, the inner wick and the outer wick being oriented to enable a transfer of fragrance material to the inner wick from the outer wick, the fragrance material including fragrance molecules, the inner wick being configured to enable a transfer of some of the fragrance molecules into air within the air passage. 14. The canister assembly of claim 13 wherein the woven fibrous material of the outer wick has a denier within a range of 3-6. 15. The canister assembly of claim 13 wherein the woven fibrous material of the outer wick comprises felt. 16. The canister assembly of claim 13 wherein the woven fibrous material of the outer wick comprises felt having a denier with a range of 3-6. 17. The canister assembly of claim 13 wherein: the outer wick has an inner surface positioned adjacent to the inner wick and an outer surface positioned opposite the inner surface; and fibers of the fibrous material are arranged to provide a grain within the outer wick that runs between the outer surface and the inner surface of the outer wick.
