Abstract
The filter (1) comprises an air-permeable core (2) surrounded by a wrapping (3) of air-permeable filter paper, corrugated longitudinally along its full length, except for a circular portion (6) at one end (7) of the filter. A non-corrugated wrapping (4) of air-permeable paper surrounds the corrugated wrapping (3), forming longitudinal channels (5) which are closed at one end. This filter efficiently removes carbon monoxide and chemical components of low molecular weight whilst being firm and easy to manufacture on an industrial scale by a continuous manufacturing process, unlike known filters having comparable filtering characteristics. <IMAGE>
