A universal filtering mouthpiece for smoking devices comprising a flexible and substantially conical shaped body having a small diameter end and a large diameter end; a hollow smoke passage which runs axially through the conical shaped body from the small diameter end to the large diameter end; a filter cartridge housing centered axially at the mouthpiece end of the said flexible and substantially conical shaped body which communicates with the hollow smoke passage and capable of housing a removable filter; and a disposable, high-airflow filter cartridge consisting of a rigid cylindrical frame having rounded edges, the rigid cylindrical frame housing a smoke filter inside the inner diameter of said rigid cylindrical frame. The universal filtering mouthpiece for smoking devices is readily implementable across a wide variety of smoking devices such as, but not limited to, pipes, bongs, hookahs, water pipes, electronic cigarettes, cigarettes, and pre-roll cigarettes.

A filtering apparatus for filtering particles out of cigarette smoke includes a tube having a smoking end and a suction end, and a perimeter wall which is gas impermeable. A first filter is coupled to and is positioned within the tube adjacent to the suction end. The first filter comprises a first filtering substance that is gas permeable and is configured for capturing particulates in smoke when the smoke flows through the first filtering substance. The first filtering substance comprises cotton wool. A second filter is coupled to and is positioned within the tube adjacent to the first filter. The second filter comprises a second filtering substance that is gas permeable and is configured for capturing particulates in the smoke when the smoke flows through the second filtering substance. The second filtering substance comprises one of coconut activated carbon and bamboo activated carbon.

A non-combustion-heating-type stick comprising: a substrate that includes an aerosol source; a cooling portion that produces an aerosol by cooling a vapor produced by heating the substrate; and a filter portion that is disposed in an area through which the aerosol passes, wherein at least one of the substrate, the cooling portion, and the filter portion contains a porous adsorbent.

The invention discloses a filter-tipped cigarette comprising a filter tip. The filter tip comprises a plurality of filter elements twisted together by mutually winding. All the filter elements are cellulose acetate fiber bundles. In the invention, since the filter elements are disposed in the way of winding, a total length of the filter elements is increased, a travel of a smoke passing through the filter elements is thereby increased, and thus harmful ingredients in the cigarette are filtered more thoroughly.

A graphene adsorbing material, a preparation method therefor and application thereof, and a cigarette filter tip and a cigarette are provided. The graphene adsorbing material comprises a fiber carrier, graphene and doped elements wherein the graphene and the doped elements are loaded on the fiber carrier and the doped elements comprise at least one of Al, Si and Fe. The graphene adsorbing material is obtained by contacting the fibers with the graphene material to load the graphene material on the fibers. By introducing the graphene and the doped elements in the fiber carrier, harmful substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke can be specifically adsorbed, filtered and removed; while nicotine and the other harmless substances are retained, and thus the smoking taste of a cigarette is not affected. The cigarette filter tip can effectively adsorb cancerogenic substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke to reduce harm of smoking; meanwhile, the pleasure of smoking and the mellow taste of the smoke are not affected. Besides, the graphene adsorbing material can also prevent the phenomenon that a cigarette holder gets mildewed due to humid environment and the other factors.
