ABSTRACT:
A body furniture is provided having one or more air exhaust ports and a built-in air fan. A top plate having one or more air suction port is positioned on the furniture body, and a tornado-based suction unit is removably placed on the one or more of the air suction ports. The tornado-based suction unit includes a cylinder having a window formed through a peripheral wall thereof, and a suction hole formed through at least one of end surfaces of the cylinder connected to a suction side of the air fan. An artificial tornado is generated within the cylinder and collects contaminated air such as the smoke of cigarettes. The collected contaminated air is cleaned. Minus ions or fragrance may be supplied to air sucked from the suction hole to fill a space around the body.
