PROBLEM TO BE SOLVED: To provide a dedusting deodorizing filter that collects, decomposes, and deodorizes a mist component in air at a high efficiency and has a low air permeation resistance. SOLUTION: In a deodorizing filter of a layered structure comprising the three layers of a retention nonwoven fabric containing an adsorbent held by a binder and a catalyst component that decomposes the adsorbed gas and dustproofing nonwoven fabrics between which the retention nonwoven fabric is sandwiched, the dustproofing nonwoven fabric situated upstream of an air flow contains solid superacid particles. |
