ABSTRACT:
A secondary-smoke filtration device which effectively filters one-hundred percent of the secondary-smoke associated with cigarettes, pipes, and cigars. The device includes a smoked product container (20), an exhalation pipe (34), a smoke conduit (30), and a filtering device (45). In use, the smoker inhales smoke from the smoked product (10) contained within the smoked product container (20) and exhales into the exhalation pipe (34). The smoke is drawn through the smoke conduit (30) by a blower fan (64) and through a series of filters (59), (60) and (61), respectively. The smoke is then returned to the environment free of contaminants and pollutants.
