Abstract
A filter for a cigarette which includes a centrally disposed generally conical baffle at the mouth end thereof with its conically shaped wall diverging in the general direction of the flow of smoke through the filter to divert the smoke exiting from the center of the filter when in use. The baffle is substantially impervious to smoke and forces the smoke leaving the filter in a direction generally angularly outward from the periphery of the filter. Ventilating air grooves can also be provided in the filter to direct ventilating air at the mouth end of the filter to provide mixing of the exiting smoke and ventilating air at the mouth end of the filter.
