Answer Details

The filter in a cigarette does not reduce the nicotine content through burning, evaporation, or absorption. Instead, it works through a process called adsorption. Adsorption is the process where a substance (in this case, nicotine) adheres to the surface of a solid material (in this case, the filter). The filter in a cigarette is made of a porous material that attracts and holds onto the nicotine as it passes through. This reduces the amount of nicotine that is inhaled by the smoker. So, the filter in a cigarette reduces the nicotine content by adsorption.
