Abstract: The invention is directed to a filter for removing cigarette smoke particles. The filter is comprised of a housing having an inlet and an outlet. A first diaphragm is positioned adjacent the housing inlet and a second diaphragm is positioned midway along the length of the housing and dividing the filter into forward and rearward chambers. At least one smoke particle condensing surface is positioned within each of the forward and rearward chambers. The smoke particles condensing surface provides additional surface upon which the particles condense after passing through at least the first diaphragm.
