PURPOSE: An air filter unit is provided to easily implement a filter cleaning operation by reducing the moving speed of air based on a partition and free-falling dust in the air. CONSTITUTION: An air filter unit includes a duct(110), a flux reducing member(120), a filtering member(130), a dust discharging member, and an auxiliary flux reducing member(150). Air is introduced into and is discharged from the duct. The flux reducing member is installed in the duct in order to reduce the flux of air introduced into the duct. The filtering member is arranged at the outlet of the duct and filters the dust of the air. The dust discharging member receives dust fallen from the duct by being arranged under the duct. The auxiliary flux reducing member reduces the flux of air by being formed at the flux reducing member.
