Claim:
A cigarette comprising a tobacco rod and a filter element connected to the tobacco rod, said filter element having an end proximal to the tobacco rod and an end distal from the tobacco rod, wherein said filter element comprises: a first longitudinally extending section of fibrous tow filter material positioned at the end of the filter element distal from the tobacco rod, said first section of filter material comprising a longitudinally extending central portion of fibrous tow filter material, a longitudinally extending outer portion of fibrous tow filter material positioned annularly around the central portion, and a compartment having a structure defined by the inner central portion, the central portion completely encapsulating the compartment; a second longitudinally extending section of fibrous tow filter material positioned at the end of the filter element proximal to the tobacco rod and spaced apart from said first section of filter material, the two sections of fibrous tow filter material defining a compartment therebetween, wherein said second section of filter material has a greater particulate removal efficiency than said first section of filter material; an adsorbent material contained within at least a portion of the compartment between said first section of filter material and said second section of filter material; and at least one breakable capsule positioned in the compartment in said first section of filter material such that the capsule is downstream from the adsorbent material present in the filter element, wherein the first section of fibrous tow filter material, the compartment, and the second section of fibrous tow filter material are circumscribed by a plug wrap, and wherein the plug wrap is circumscribed by a tipping material that circumscribes the entire length of the filter element and attaches the filter element to the tobacco rod.
