  • Filter design for improving sensory profile of carbon filter-tipped smoking articles
    Patent number: 8434499
    Abstract: A filter for a smoking article, which includes an upstream segment having a carbon filter and a downstream segment of filtering material. The upstream segment includes a carbon filter with a hollow tubular member concentrically positioned within the carbon filter, and one or more holes around an outer circumference of the hollow tubular member to allow mainstream smoke to bypass the carbon filter during the first puff. During use, the hollow tubular member has a lower resistance to draw than the carbon filter during an initial puff or puffs, and after the initial puff or puffs, mainstream smoke is drawn through the carbon filter.
    Type: Grant
