Smoking articles which involve the use of amphiphile-modified sorbents are disclosed. The amphiphile-modified sorbent has at least one amphiphilic compound bound to an inorganic molecular sieve substrate. The amphiphile-modified sorbent selectively removes certain constituents from cigarette smoke, while maintaining other constituents, such as those that contribute to flavor. Methods for making cigarette filters and smoking articles using amphiphile-modified sorbents, as well as methods for smoking a cigarette containing an amphiphile-modified sorbent, are also provided.

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.

A filtration apparatus for filtering air is described. It includes a disposable capsule defining an absorptive material space to hold a volume of absorptive material, where the disposable capsule further defines a set of capsule fluid inlets to permit fluid to move through the disposable capsule into and out of the absorptive material space. The apparatus further includes a reusable frame to support the disposable capsule, where the reusable frame defines a frame fluid inlet and the reusable frame is removably couplable to the disposable capsule to direct fluid passing through the filtration apparatus through a fluid passage through the frame fluid inlet and the absorptive space of the disposable capsule. Also disclosed is a set of injection molding molds for forming a filtration apparatus.

A smoke gas filter device and a tobacco product. The smoke gas filter device is formed with a smoke gas filter channel (L). The smoke gas filter channel (L) is provided with a graphene material segment (1). The graphene material segment (1) is a graphene material powder segment, a graphene material aerogel segment or a graphene material film segment. A graphene material is graphene and/or functionalized graphene. The smoke gas filter device has a large adsorption capacity, and the adsorption is firm, which helps to reduce amount of the toxic substances entering the human body in the smoke gas, reducing the harm to the human body while smoking.

The present disclosure relates to a lyocell material with controlled whiteness by hydrogen peroxide treatment and a manufacturing method thereof, wherein the lyocell material has improved whiteness due to an aging effect through drying and packaging by a predetermined amount of hydrogen peroxide remaining in a tow, and may replace a CA cigarette filter to lower environmental pollution problems caused by discarded cigarette butts, and thus the lyocell material is suitable as a cigarette filter.

The present disclosure relates to a method of molding a combustible heat source and provides a method of molding a combustible heat source, the method including: step S1 of preparing a combustible heat source composition including a carbon powder, an organic binder, and an ignition accelerator, step S2 of treating glycerin or propylene glycol on the combustible heat source composition; and step S3 of compressing and molding the composition after the treatment, in which the compressing in step S3 is performed at a strength of 0.5 to 10 MPa.

A smoking article includes a smokable material and a filter downstream of the smokable material. The filter includes activated carbon material having a BET of between 1000 and 2000 m.sup.2/g and exhibiting less particle breakthrough than granulated coconut shell derived activated carbon currently used for filters of smoking articles.
