Rather than ban smoking, simply banish the smoke. The larger particles are trapped by a mesh filter. Then the really nasty remaining particles are drawn in and receive an intensive electrical charge. They are then attracted onto aluminium plates like a magnet. As there are no filter holes to slip through at this stage, it means that virtually all tobacco smoke, dust, bacteria, viruses, pollen and other pollutant airborne particles are caught.
Clean air is recirculated, providing a real breath of fresh air and a pleasant atmosphere.
