置。 A filter unit casing that consists of a top plate and a side plate, and has an intake port with a pre-filter attached to the side plate of the outer shell, which is formed so that the lower opening edge is attached to an opening formed in the ceiling of a room to keep the air clean. A filter unit is provided inside the filter unit casing with a ventilation hole provided in the top plate of the inner body made up of a top plate and side plates so as to form a return air suction passage between the filter unit casing and the main filter in the bottom opening. The fan installed in the filter unit casing cleans the air from the room sucked from the return air suction passage and the air from the outside suctioned from the intake port through the vent and the main filter, and then enters the room. A clean air circulation device characterized by being configured to supply air.
