Abstract

A smoking article includes a filter element having MCM-41 as a mesoporous molecular sieve. Also, a smokable article includes a smokable material and a wrapping paper having MCM-41 as the mesoporous molecular sieve. The mesoporous molecular sieve may be used in combination with charcoal or impregnated with copper oxide to further enhance filtration.
