A centrifugal blower (1, 101, 201, 301) includes an air intake housing (20, 120, 220, 320), including an internal space, a filter (40,140) disposed in the internal space, and first to third rotary doors (28a, 28b, 28c), wherein the first rotary door, the second rotary door, and the third rotary door are aligned in that order. The internal space includes first to third spaces (20A1-20A3) which are operating ranges of the rotary doors. The filter has first to third regions (51-53) that oppose the first to third spaces, and the first region coincides with a tongue portion (10T) of a scroll housing. A filtering face area of the third region (53) is greater than a filtering face area of the first region (51).
