ABSTRACT:
The specification discloses a cigarette filter modifier and related method in which the pattern of tar and nicotine collection in a conventional cigarette filter is modified by the insertion into the filter of a hollow probe having apertures therein which communicate with the interior passageway of the probe, combined with a base shield radiating from and surrounding said probe so as to block the passage of smoke, thereby forcing cigarette smoke to travel through the apertures and interior passageway of said probe. The base shield is approximately the diameter of the cigarette, and its perimeter thereof defines the lateral extremes of the device so as to minimize its visibility.
