2. The appliance of claim 1 , wherein the inner wall comprises a plurality of perforations extending at least partially around the inner wall.

3. The appliance of claim 1 , wherein the outer wall comprises a plurality of perforations extending at least partially around the outer wall.

4. The appliance of claim 1 , wherein the outer wall comprises a plurality of perforations extending at least partially along the outer wall.

5. The appliance of claim 1 , wherein the handle comprises a first end and a second end.

6. The appliance of claim 5 , wherein the inner wall has a first end and a second end and the inner wall extends from the first end of the handle towards the second end of the handle.

7. The appliance of claim 5 , wherein the outer wall of the handle extends from the first end towards the second end of the handle.

8. The appliance of claim 7 , wherein the outer wall extends to the second end of the handle.

9. The appliance of claim 5 , wherein the perforations in the outer wall are adjacent to the second end of the handle.

10. The appliance of claim 9 , wherein the perforations in the outer wall extend along the handle towards the first end.

11. The appliance of claim 1 , comprising a filter disposed within the outer wall extending across and around the perforations in the outer wall.

12. The appliance of claim 11 , wherein the handle comprises a first end and a second end and the filter extends from the second end of the handle.

13. The appliance of claim 12 , wherein the inner wall has a first end and a second end and the filter extends from the second end of the handle to abut the second end of the inner wall.

14. The appliance of claim 6 , further comprising a filter disposed within the outer wall extending across and around the perforations in the outer wall wherein the filter extends from the second end of the handle to abut the second end of the inner wall.

15. The appliance of claim 14 , wherein the second end of the inner wall is curved.

16. The appliance of claim 6 , wherein the second end of the inner wall is curved.

17. The appliance of claim 1 , wherein the inner wall comprises at least one supporting rib which projects between the inner wall and the outer wall.

18. The appliance of claim 17 , wherein the at least one supporting rib extends longitudinally along the inner wall.

19. The appliance of claim 1 , wherein a lining material is provided between the outer wall and inner wall of the handle.

20. The appliance of claim 1 , wherein the handle comprises a fan unit wherein the inner wall comprises a housing for housing the fan unit in the handle.

21. The appliance of claim 20 , wherein the housing is between a first end of the handle and a second end of the handle.

22. The appliance of claim 21 , wherein the inner wall includes a plurality of perforations between the second end and the housing.

23. The appliance of claim 21 , wherein the inner wall is unperforated between the housing for the fan unit and the first end of the handle.

24. The appliance of claim 1 , wherein the inner wall is formed from a first part and a second part.

25. The appliance of claim 21 , wherein the inner wall comprises a first portion adjacent the second end of the handle comprising a plurality of perforations, a second portion being unperforated and comprising the housing for the fan unit and a third portion extending from the second portion towards the first end of the inner wall which is unperforated.

26. A hand held appliance comprising a handle having an inner wall and an outer wall extending along and around the inner wall, wherein the inner wall comprises a plurality of perforations extending at least partially along the inner wall, wherein the outer wall comprises a plurality of perforations, and wherein the plurality of perforations of the outer wall are upstream of the plurality of perforations of the inner wall such that the plurality of perforations of the outer wall are longitudinally spaced from the plurality of perforations of the inner wall.

27. The appliance of claim 1 , wherein the appliance is a hairdryer.

28.
