    Abstract: Provided are a method and apparatus for making a cigarette filter assembly for potentially reducing particle breakthrough. The method includes forming a lofty porous network of charge retaining polymer fibers by mechanical, chemical or thermal bonding of the fibers, wrapping the lofty porous network in a cylindrical or tubular shape with optional mediating filter fibers in a filter paper to form a filter plug while maintaining the lofty structure. The charge retaining fibers can be charged to attract and hold particles from such sources as particulate matter from sorbents (preventing break-through), and smoke constituents while having a suitable pressure drop. The apparatus handles the lofty media with minimal crushing, for example, by spacing apart delivery rolls equipped with protrusions to punch, push, and/or pull the lofty media ahead for high speed operation.

    Abstract: Provided is a cigarette filter and method of making the filter. The filter includes an adsorbent dispersed within the filter and a downstream plug of randomly-oriented fibers. The randomly-oriented fibers mechanically capture adsorbent particles entrained in tobacco smoke. One or more plugs of axially-oriented fibers may also be located upstream and/or downstream of the adsorbent, and are included in an amount sufficient to adjust the length of the filter.
