• a second main wall facing the first main wall;
• a first side wall and a second side wall each sealing a space between a side edge of the first main wall and a side edge of the second main wall;
• a first partition wall disposed without a gap between the first partition wall and the first main wall and with a gap between the first partition wall and the second main wall;
• a second partition wall disposed without a gap between the second partition wall and the second main wall and with a gap between the second partition wall and the first main wall;
• a photocatalyst unit provided between the first main wall and the second main wall, and allowing air to pass therethrough in a direction from the second main wall to the first main wall;
• and
• a centrifugal blower disposed opposite to the photocatalyst unit with respect to the second partition wall and spaced apart from the first main wall, the centrifugal blower having a suction port that opens toward the first main wall and a discharge port that opens on a side facing away from the second partition wall.
