Abstract
An apparatus for eliminating sidestream smoke from a cigarette or other smoking article includes a smoke collecting chamber adapted to collect sidestream smoke from the lit end of the smoking article along with air for combustion of the sidestream smoke and to direct the mixture of sidestream smoke and air to a combustion area associated with the smoke collecting chamber. An ignition device is included in the apparatus for igniting at least a portion of the sidestream smoke received in the combustion area by heating the smoke in the combustion area to an ignition temperature. The preferred ignition device includes a heat source for constantly producing a flame in the combustion area. The apparatus may also include a smoke particle capturing arrangement in a capture chamber connected to the smoke collecting chamber. The smoke particle capturing arrangement is adapted to remove smoke particles from the sidestream smoke or to capture smoke particles in the combustion area on a suitable ignition surface so that the igniting device may ignite the captured smoke particles.
