Provided is a dehumidifier with which a deterioration in air cleaning performance and the generation of clearance noise can be prevented even if a pressure difference acts on a shutter that is closed when performing an operation focused on air cleaning. The dehumidifier comprises: a housing having an inlet and an outlet; a blowing means which is disposed inside the housing to generate an airflow from the inlet to the outlet; an air cleaning means disposed inside the housing; a dehumidifying means which is disposed inside the housing to remove moisture from the airflow; a first air passage allowing the airflow to pass through the air cleaning means to reach the dehumidifying means; a second air passage allowing the airflow to reach the dehumidifying means without passing through the air cleaning means; and an opening and closing means for opening and closing the second air passage. The opening and closing means has a shutter which is disposed inside the second air passage and which is capable of pivoting about
