Most environmental tobacco smoke ETS issues from the tips of smoldering cigarettes between puffs. This paper describes an experimental investigation of the effectiveness of four smokeless ashtrays: two commercial devices and two prototypes constructed by the authors. In the basic experimental protocol, one or more cigarettes was permitted to smolder in a room. Particulate or gas-phase pollutant concentrations were measured in the room air over time. Device effectiveness was determined by comparing pollutant concentrations with the device in use to those obtained with no control device. A lung deposition model was applied to further interpret device effectiveness for particle removal.

Air Purification. Updated April 28, By Thomas Johnson. For instance, extreme weather conditions can make it difficult to leave your home, or sometimes it feels too inconvenient to drag yourself out of bed just for a puff of smoke. The downsides of indoor cigarette smoking extend beyond its adverse effects on the health of family members. Often, smoking indoors leaves an unpleasant odor and discolors your house walls, leaving an unflattering impression on visitors. These ashtrays come with filters that absorb smoke before it disperses into the air. This way, they prevent the emission of smoke and the odor that otherwise remains in your home.
