FILTRATION EFFICIENCY OF A CIGARETTE FILTER WITH X- OR Y-SHAPED FIBERS

ABSTRACT
Nicotine is harmful to the health of smokers and the inhalation of second-hand smoke is more harmful. A high efficiency of nicotine filtration for a cigarette filter is much needed. This paper suggests a formulation to predict filtration efficiency of a filter with X- or Y-shaped fibers. Main effects affecting the efficiency are elucidated using a fractal modification of the Darcy's law.
