A smoke-free working area is described in connection with a table having a recirculating air system. The table base comprises a sealed air chamber pressurized by a motor and filter system. Openings located on the surface of the table allow air to be dispensed at a controlled rate which travels up and is collected by a network of air ducts that support a canopy. A return path for the air is fed through a hollow support member that is connected at one end to the air ducts and at the other end to the motor and filter assembly thereby completing the flow path. Smoke and other pollutants are carried into the system and filtered in a continuous fashion, thereby providing a continuous smoke-free environment for other persons located adjacent the smoke-free table area.
