    Abstract: A hygiene management device for an entrance hall includes a footrest located on the bottom of an entrance space to introduce air to the footrest and may transmit the air to an air management module. In the air management module, the air may be purified and the temperature thereof may be preset. The air may be flown through a duct by a fan assembly. The air flowing through the duct may pass through a second duct located at the ceiling of the entrance space and be transmitted to an air discharger. The air discharger may adjust directions to which discharge holes are directed such that air can be discharged to a person standing on the footrest in various directions, and the discharged air may be introduced into the footrest.
