Various embodiments disclosed in this document relate to a hood system and a control method thereof.

A hood system is a device that is installed in a place where smoke, smell, dust or contaminants in the surrounding environment are generated, and prevents their diffusion by exhausting the air. For example, a household hood system is mainly installed above a cook top in a kitchen, and absorbs odors and smoke generated from a cooking container at the bottom of the hood.

In the household hood system, since the hood system is spaced apart from the cooktop at a predetermined distance, there is a predetermined distance from an inhalation target that generates odor or smoke, such as a cooking container.
