US Patent 7861726 Filtration device for tobacco products

A system and method for a cigarette smoke filtration device that reduces second-hand smoke and holds a lit cigarette while being smoked or sitting idle. The device somewhat resembles a bifurcated cigarette holder wherein a lit cigarette is placed within the device while being smoked or sitting idle. Once inside, the device draws the smoke from the cigarette through a filtering system reducing offending odors as well as most of the harmful gases from cigarette smoke. The filtering system has replaceable filter cartridges. The spent ashes are collected in the device's base which can be emptied as needed.
