A baked item includes a tobacco and a microwave absorbing agent. The tobacco and the microwave absorbing agent are both capable of absorbing microwaves to generate heat, the microwave absorbing agent is made of a non-volatile solid material with a stable dielectric loss constant. The microwave absorbing agent is capable of stably absorbing microwaves to generate heat to heat the tobacco through thermal conduction. A method for preparing the baked item and a microwave heating method for the baked item include, the microwave absorbing agent is added into the tobacco, and the microwave absorbing agent can stably absorb microwaves to generate heat. In addition to absorbing microwaves to generate heat, the tobacco may be also heated by the microwave absorbing agent through thermal conduction, and temperature rising of the tobacco is more stable and uniform under a double heating mechanism of microwave radiation and thermal conduction.

A system including a pre-roll cone or cylinder used as a sleeve for use with smokeable substances, a tip for being attached to a sleeve for holding a smokeable substance. The tip has a freshness plug at a first end of the tip and a filter at a second end of the tip. The sleeve can be formed using with papers made from a variety of materials. Smoking papers are cut in a way to form sleeves that attach to the larger end of the glass tip, or the end where the tip meets raw material. The use of sleeves allows for the re-use of tips made from materials capable of multiple uses without degradation of quality, such as glass or metal. The filter has a cross-hair or similar shape at the end adjacent to the smokeable substance. The freshness plug is at the other end of the tip.

The present disclosure relates to a filter for a smoking device, such as, but not limited to, a water pipe. The filter includes a body that is positionable over a mouthpiece of the smoking device, to filter impurities from smoke drawn therethrough, and a base that secures the body over the mouthpiece such that smoke is drawn therethrough, prior to inhalation by a user. The body can include one of more filtration layers, such as a first layer formed from a material selected to filter carcinogens and other impurities from the smoke prior to inhalation, and a second layer formed from a material selected to minimize or prevent the transmission of bacteria, viruses, or other contagions from a user's mouth to the smoking device. Each of the filtration layers can also be formed from one or more materials.

A filter assembly has an outer housing having an open first end and an open second end. An inner filter housing is within the outer housing adjacent the second end, and a gasket is provided at the first end of the outer housing. An internal chamber is provided between the first end of the outer housing and the inner filter housing, where during use, fluid from the within the internal chamber is drawn out the second end of the outer housing by way of the inner filter housing. A filter is provided within the inner filter housing. The gasket forms a gasketed opening smaller than the open first end of the outer housing. The gasket may extend axially adjacent a wall of the outer housing and abut the inner filter housing, such that the internal chamber is defined by the gasket and the inner filter housing.

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 including the sorbent are also provided.

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 absorbing 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 alginate.

A smoke filtration device for making self- and machine-rolled conically shaped cigarettes (10) comprises a frusto-conical tubular body (2) with a proximal end (4), a distal end (6) and an internal smoke filtering passage (8) connecting said ends. To improve the device, said smoke filtering passage is integrally formed with said tubular body, said tubular body is made of a sintered ceramic material, and said smoke filtering passage is configured as an open-cell porous structure having an effective porosity of 75 to 85%. In a method of manufacturing the smoke filtration device, the frusto-conical tubular body including said open-cell porous structure is formed by additive manufacturing.
