The filter using technology for reducing the smell of tobacco smoke on hands, according to one embodiment of the present invention, comprises: a filter unit for filtering tobacco smoke, the filter unit being coupled to a tobacco shred; and filter-wrapping paper for wrapping the filter unit. The filter unit or the filter-wrapping paper may contain a material for reducing the smell of tobacco smoke. According to the embodiment of the present invention, green tea extracts containing catechin or other materials for reducing the smell of tobacco smoke, e.g. citric acids, glycerols, tannic acids and the like can be added to a tobacco filter to remove the smell from tobacco smoke generated during smoking, thus significantly lowering the strength of the smell of tobacco smoke on the hands of a smoker as compared to conventional tobacco filters.

A filter for sorption of components of tobacco smoke which are harmful to health comprises ceramic particles bonded to form a porous structure (12). In order to avoid contamination within a short period of time even when the filter is not properly disposed of, and without causing a loss in sorption or in the smoking sensation, the filter has decreasing water solubility from a tobacco-side portion (1) to an opposite mouth-side portion (2).

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.

The present invention relates to an improved water pipe comprising a chamber containing water in its lower portion, its upper compact cylindrical portion serving as a smoke collection reservoir; a bowl for combusting tobacco or medicinal herbs, the smoke directed through a tube to the water chamber below the water; and a mouth piece for applying suction to the interior of the chamber to inhale the smoke.

An aerosol generating product includes an aerosol atomizing element and a smoke cooling element, and the smoke cooling element is located downstream of the flow direction of the smoke generated by the aerosol atomizing element. A filter element is located downstream of the flow direction of the smoke through which the smoke cooling element passes; or a hollow element located upstream of the flow direction of the smoke through which the smoke cooling element passes. The smoke cooling element is composed of particles, and the structure includes a gap for smoke of a cigarette to pass through. The gap through which cigarette smoke can pass is a three-dimensional and non-linear gap. The structure is in the form of rods. When the smoke aerosol passes through the cooling element, ensuring the smoke to pass through smoothly.

The cigarette smoke-filtering device includes a bottom dome that includes at least one inlet port thereon. The at least one inlet port of the bottom dome is adapted to receive a lit cigarette thereon. The bottom dome is attachable to a top dome. The bottom dome and the top dome form an interior cavity that supports a carbon filter and a smoke chamber. The carbon filter is responsible for filtering cigarette smoke delivered from the lit cigarette via the at least one inlet port. The bottom dome includes an outlet that is affixed to a hose that extends there from. The hose is in turn attached to a mouthpiece.
