The air sanitation device includes: a housing having an upper wall, a lower wall, and a peripheral wall connecting the upper wall to the lower wall; an air channel disposed in the housing and has an air inlet and an air outlet; a fan disposed in the air channel to force air to enter the air channel from the air inlet and leave the air channel from the air outlet; and an air detection device and/or an air purification device disposed in the air channel. The air outlet is disposed on the peripheral wall, and the air channel is configured in such a way that the air is discharged out of the air outlet obliquely downward.
