Abstract
A smoking article includes a filter arrangement comprising a first filter section and a second filter section, the second filter section being located downstream of the first filter section, and a ventilation arrangement configured to provide a user controllable level of ventilation into the first filter section. A resistance to gaseous flow through the length of the second filter section is lower than a resistance to gaseous flow through the length of the first filter section, and the resistance to gaseous flow through the length of the filter arrangement remains substantially constant as the level of ventilation is varied.
