An object of the present invention is to provide a dust collection deodorization filter medium and a dust collection deodorization filter which have improved dust collection performance while keeping the pressure loss of the filter medium low. In a dust collection deodorizing filter medium in which an adsorbent is sealed between a base material A and a base material B, at least one of the base material A and the base material B has a basis weight of 20 to 200 g / m2, Thermally bonded nonwoven fabric sheet containing ethylene / propylene copolymer fiber and polypropylene fiber, and the collection efficiency of particles of 0.3 μm or more is 30% at a surface wind speed of 5.3 cm / sec in a dust collection deodorizing filter medium. A dust collection deodorizing filter medium having a pressure loss of 10.0 Pa or less and a dust collection deodorization filter using the dust collection deodorization filter medium.
