Abstract
An air purifier may include a main body and a floating body configured to levitate above the main body via magnetic force. The main body may include a fan to suction air, a filter to filter suctioned air, and a discharge port provided on an upper surface through which air is discharged. The floating body may be provided above the discharge port and further disperse discharged air. The main body may have a magnetic force generator to provide a magnetic force that levitates the floating body, and may also have a magnetic force adjustor configured to maintain a stable position of the floating body.
