An air purifier that efficiently restores the capacity of a deodorizing element (62) by locally heating the element is disclosed. The air purifier is provided with a case having an intake and outlet connected by an air passage (r) with a fan for passing air through the passage. A heating unit (63) heats the deodorizing element (62) and a position-changing means (64) changes the positional relationship between the heating unit (63) and the deodorizing element (62). A control means controls the fan, the heating unit (63), and the position-change means (64). The deodorizing element (62) has the ability to recover its deodorizing capacity when heated by the heating unit (63) and is rotatably attached to the frame of the air purifier. The heating unit (63) faces the deodorizing element (62) and a cover (65d) is provided on the opposing side of the heating unit (63) with the deodorizing element (62) in-between. The cover (65d) radiates heat from the heating unit (63) back towards the deodorising element (62) for efficient heating of the local area.
