Shown is a filter material for manufacturing a segment for a smoking article, wherein the filter material is web-shaped and contains at least 50% and at most 100% cellulose fibers, each with respect to the mass of the filter material, wherein the filter material has a basis weight of at least 15 g/m.sup.2 and at most 60 g/m.sup.2, wherein the thickness of one layer of the filter material, measured in accordance with ISO 534:2011, is at least 25 m and at most 1000 m, wherein the filter material has a machine direction and a cross direction orthogonal thereto and lying in the plane of the web of the filter material, and wherein the filter material has a characteristic plastic deformability in the cross direction which is characterized in that in a tensile test in the cross direction in accordance with ISO 1924-2:2008, the nonlinear portion of the deformation energy absorbed by the filter material up to half the elongation at break is at least 10% and at most 50% of the total deformation energy absorbed by the filter material up to half the elongation at break.

A reusable smoking filtration apparatus includes a tip having a tubular shape with a first end and a second end, a freshness plug configured to be coupled to the first end of the tip, and a cross-hair shaped filter configured to be coupled to the second end of the tip.

Apparatus consistent with the present disclosure may be a pipe that includes heat transfer materials that have a thermal conductivity of greater than 50 Watts per meter Kelvin. Heat transfer materials may include one or more solid heat sinks (that are rigidly connected to each other or to a portion of the pipe), Peltier devices, or loose fill of a desired size or shape. Fill included in the pipe may also absorb particulate matter or volatile organic compounds. As a user burns or vaporizes materials at one end of the pipe and sucks heated smoke or vapor into the pipe, that user may inhale cool and clean smoke or vapor. Methods and apparatus consistent with the present disclosure may allow a controller at the pipe to send sensor or consumption data to other electronic devices when a number of milligrams of a substance inhaled by a patient are monitored.

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 cooling cigarette filter and a smoking product are provided. The cooling cigarette filter comprises a cooling section. The cooling section is provided with one or more channels connecting two ends of the cooling section, and an inner surface of each channel is coated with a cooling material. The cooling material comprises an inorganic phase change material and PEG, and the inorganic phase change material comprises at least one of Na2CO3.Math.10H2O, CH3COONa.Math.3H2O, CaCl2.Math.4H2O, and Na2SO4.Math.10H2O. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth, especially in the cooling section. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly.
