Aerosol-cooling elements for use with an apparatus for heating smokable material are disclosed. In one example, the element is a monolithic rod having first and second ends and has plural through holes extending between the first and second ends. Other arrangements are described.

The invention relates to a cigarette filter. In particular, the present invention relates to a new cigarette filter, in which materials of natural origin are used that have not been applied in this special field before. More particularly, the present invention relates to a cigarette filter, which can be used for adsorbing the toxic components of cigarette smoke, and lowering the tissue damage triggered by cigarette smoke on the respiratory organs, the cardiovascular system and the mucosa. Especially the present invention relates to a cigarette filter containing alginite.

An aerosol-generating article according to one aspect of the present disclosure may include a tobacco medium portion, a filter portion disposed to be spaced apart from the tobacco medium portion, and a tubular cooling portion disposed between the tobacco medium portion and the filter portion. A cooling material may be included in a body constituting the cooling portion.

A filter device including a Bernoulli element is provided. The filter device includes a housing, a plurality of permeable membranes positioned in association with the housing to create a plurality of chambers in the housing, and a Bernoulli element positioned within one chamber, wherein the Bernoulli element causes airflow and pressure to vary within the one chamber when fluid comprising smoke is drawn into the filter device.

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 etc). 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.

A filter included in an aerosol-generating article, according to embodiments, includes a first filter segment including a first filter element in which at least one heterogeneous material particle is contained, a second filter segment including a second filter element, and a wrapper wrapping the first filter segment and the second filter segment, wherein the first filter segment and the second filter segment are aligned in a longitudinal direction of the filter, and the first filter segment and the second filter segment are not physically separated.

A harm-reducing cigarette filter, a method for preparing the cigarette filter and an application of the cigarette filter are disclosed, and the cigarette filter includes six layers from outside to inside: a first layer includes filter cotton with an activated carbon, a second layer includes a five-hole glue, a third layer includes filter cotton, a fourth layer includes filter particles, a fifth layer includes filter cotton with filter fluid, and a sixth layer includes a silica gel cover. The cigarette filter is injection molded by utilizing non-toxic polycarbonate (PC) or polymethylmethacrylate (PMMA). The experimental research shows that the cigarette filter has good adsorption effect on tar and nicotine, and reduces smoking people to absorb harmful substance.

There is provided an adsorbent material comprising a porous carrier material having pores with a diameter greater than 20 nm and carrying additive particles on its external surface, wherein the additive particles comprise an additive and have a diameter of greater than 20 nm. There is also provided a smoking article filter element comprising such an adsorbent material, a smoking article comprising such an adsorbent material, and a method of preparing such an adsorbent material.

Filters and cigarettes include an activated carbon sorbent capable of selectively removing nitric oxide from mainstream tobacco smoke. Methods for making cigarette filters and cigarettes using the activated carbon sorbent and methods for treating mainstream tobacco smoke produced by smoking a cigarette comprising the sorbent are also provided.

Embodiments of the present disclosure relate to a filter for cigarettes and a method of preparing the filter, and include a paper filter for cigarettes using paper and a cigarette including the paper filter. The filter for cigarettes provides a high level of satisfaction in smoking through high granular seating stability and eliminates a burnt taste.
