A dryer includes a cabinet, a drum rotatably provided in the cabinet, a duct that defines a flow passage for air exiting the drum, and a filter assembly located at a position relative to the flow passage and contacting air that has exited the drum. The filter assembly includes a case defining the filter assembly, a filter portion configured to filter foreign substance from the air contacting the filter assembly, a brush frame configured for rotational movement relative to the case about a rotational axis, and a brush that is supported by the brush frame and configured to separate the foreign substance from the filter portion. A first distance from a first side of the case to the rotational axis of the brush frame is longer than a second distance from a second side of the case to the rotational axis of the brush frame.
