A smoke filter consists of substrate threads and/or strips each pre-coated with particulate sorbent (e.g. activated carbon granules), gathered together in solid or tubular rod form e.g. within a containing sleeve. When the gathered threads and/or strips form a tubular body, this may be provided with a core.
