Coaxial Core filter

Smoking experience maintained

The Coaxial Core filter uses different types of material in a coaxial configuration, which, when used with cigarette ventilation, can give a significant reduction of carbon monoxide and other vapour phase gases without reducing tar levels by the same factor in a ventilated cigarette.

Filter construction 

A wide range of shapes, material combinations, lengths, and circumferences can be specifically tailored to the cigarette. The inner core can be produced in circular and is encased in an outer cylinder.

Choice of material combinations, lengths, and circumferences enables the control of smoke flow, levels of tar and nicotine retention, reduction of carbon monoxide present, and draw resistance. The filter’s flexibility ensures each construction is precisely designed to enhance a particular brand and suit customer taste and filtration requirements.
