<p>A unique cigarette filter (15) is formed by encasing a plurality of surface activated particulate (SAP) particles in a filter (15). The particles are less than 50 microns in diameter and have a relatively large surface area designed to interact with tar, nicotine, and other harmful substances drawn through the filter (15). In an embodiment of the present invention, the particles are pushed together to form a powder membrane (20) that is between 20 and 200 microns thick. In another embodiment of the present invention, the particles are dispersed throughout the filter. These SAP particles have a high affinity to tar, nicotine, and other harmful substances and thereby cuts down on a smoker's intake of these substances by 35 to 70 %.</p> |
