Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composite deodorizing and dust collecting filter enhanced in the life of a dust collecting filter and a deodorizing filter and not generating a malodor even if the apparatus becomes a stop state. SOLUTION: A highly efficient particle removing filter 6 such as HEPA filter or ULPA filter is used as a dust collecting filter and a first deodorizing filter 3 containing a photocatalyst functioning as a catalyst by receiving light is arranged on the side of an air taking-in port 1 while a second deodorizing filter 7 is arranged on the side of an air blow-off port 8. It is more pref. to add a porous inorg. material to the first deodorizing filter 3 in addition to the photocatalyst in order to enhance deodorizing efficiency. Further, by adding a transition metal chelating compd. to the second deodorizing filter to form a composite deodorizing filter with a deodorizing adsorbing material by activated carbon or the like, deodorizing capacity becomes stably suitable.
