Cigarette filter consists of crimped fibers with Y-shaped cross-section. In the present work, the influences of fiber crimp angle and fiber cross-sectional shape on the diffusional collection efficiency and the pressure drop of cigarette filter were studied both experimentally and numerically. As a result, the present numerical model was capable of successfully predicting the influences of crimp angle and irregular cross-section on the collection efficiency and the pressure drop. It was further shown that the maximum value of filter performance index lies at the crimp angle of π/6 for fibers with circular and Y-shaped cross-sections. Cigarette filters consisting of fibers with Y-shaped cross-section in the present work had almost the same filter performance index as predicted by the numerical analysis because they had the crimp angles between π/12 and π/4.
