Abstract: Fibrous material suitable for incorporation into filter elements of smoking articles such as cigarettes are impregnated with additives and agents such as flavorants, flavorant-enhancers and/or free radical scavengers. The fibrous material is contacted with the additive dispersed in a high pressure gas or supercritical fluid (SCF) held at elevated pressures. The high pressure gas or SCF swells the fibrous matrix and enables the additive to be incorporated within the matrix. When pressure is reduced, the gas or SCF vaporizes and leaves the additive embedded in the fiber interstices. As a result, the additive is slowly released over a finite period of time. When incorporated into a cigarette filter, the additive is released at a desired rate from the interior of the fibrous filter into the cigarette smoke.

The air/smoke mixture is drawn through the second filter into the consumer's mouth.

Abstract: Cigarette gas filter is used to filter the gaseous components of main stream smoke. This causes reduction of the delivery of the gaseous constituents of main stream smoke (MSS). The gas filter consists of a narrow annular gap, where the outer side is circumvented by a high permeability wrapper paper. As the cigarette smoke is passed through this annulus gap, the fraction of gases present in the smoke is reduced by diffusion mechanism and due to inflow of air into the annulus by convection mechanism. Since the diffusion coefficient of aerosol particles are several orders of magnitude smaller than the gas molecules, the aerosol particles are kept mainly intact while passing through the annulus. Therefore this filter is applied for reducing the gas/tar ratio. This filter can also be used to filter the gases of non-cigarette smokes.

Abstract: A cigarette filter for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter primarily comprises an activated carbon fiber filter section including a bundle of activated carbon fibers. Particulate adsorbent materials such as granules, beads or course powders may be dispersed amongst the activated carbon fibers to aid in removal of the gas phase constituents.

In one embodiment, the activated carbon fibers are positioned within a helical groove on the outside of a threaded rod within the activated carbon fiber filter section. Relatively smaller amounts of activated carbon fibers produce the same smoke constituent reduction as larger amounts of particulate adsorbent material.
