Abstract: A smoker's box for reducing pollution caused by smoking a cigarette. A housing has a first and second portion, the first portion defining a cavity, and the second portion defining a fan chamber. A venting channel allows gases to pass between the first and second housing portions. A lighter is provided to light a cigarette within the cavity. A mouthpiece and a cigarette sleeve for holding a cigarette define an inhalation channel open to the surrounding atmosphere. A replaceable cartridge includes a burn chamber in which the cigarette burns, a smoke treatment chamber adjacent to the burn chamber, a particulate filter between the burn chamber and the smoke treatment chamber, and smoke treatment means within the smoke treatment chamber for absorbing exhaled smoke passing within the smoke treatment chamber to produce a decontaminated gaseous mixture.
