The embodiments herein provide a filter for cigarette comprising graphene nano-composite based material enclosed in a casing. The filter is reusable and is plugged to any cigarette, or tobacco smoking products. The filter is a stand-alone product or manufactured integrally with each individual cigarette. The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke. The graphene based nanocomposite filter adsorbs the toxic agents from the smoke of cigarette, beedi, hookah. The filter is fabricated by treating ceramic particles and coating them with carbon particles. The carbon particles are carbonized. The ceramic particles coated with carbon are segregated based on shape and size and treated chemically to convert carbon into graphene under inert conditions. The graphene coated particles are chemically functionalized for improved filtration.

There is provided a smoking article having an aerosol generating substrate and a mouthpiece. The mouthpiece includes a cavity at least partially filled with a particulate material, such as activated carbon,and contains at least one breakable capsule of a liquid flavourant at least partially surrounded by the particulate material, such that the force required to break the capsule within the mouthpiece to release the liquid flavourant is less than three times the inherent burst strength of the capsule.

A filtering unit for use with an electronic cigarette which includes a hollow housing and a filter pad located inside the housing. The housing has a first end, a second end, a front wall, and a rear wall. The front wall and the rear wall extend from the first end to the second end of the housing. The hollow housing also including a throughgoing opening formed at the second end and at least one pair of first internally extending prongs, these first prongs forming an internal chamber. The filter pad is positioned inside the internal chamber of the hollow housing. The second end of the hollow chamber is positionable over a portion of the electronic cigarette so as to filter out undesired particles in vapors of the electronic cigarette.
