The present disclosure relates to smoking substitute consumables, including an aerosol-forming article comprising an aerosol-forming substrate and a terminal filter element at a downstream axial end of the article/consumable. The terminal filter element may comprise a hollow bore extending from an upstream axial end of the terminal filter element to a downstream axial end of the terminal filter element. The hollow bore may be off-set from the axial centre of the terminal filter element.

The present disclosure provides an aerosol-forming article comprising an aerosol-forming substrate and an axially adjacent, downstream filter arrangement. In some implementations, the filter arrangement comprises an upstream filter element, an intermediate filter element and a terminal filter element. The upstream and terminal filter elements may be independently selected from a solid filter element and a hollow bore filter element. The intermediate filter element may be a hollow bore filter element having a greater bore diameter than any other hollow bore filter element in the filter arrangement.

An aerosol-generating system is provided, including: an aerosol-generating article configured to produce an inhalable aerosol upon heating, the article extending from a mouth end to a distal end and including: an aerosol-generating element, and a downstream section located downstream of the element, the downstream section extending from a downstream end of the element to the mouth end of the article, the downstream section including a hollow tubular element and a resistance-to-draw of the downstream section being less than about 10 mm H.sub.2O; and an aerosol-generating device having distal and mouth ends, the device including: a body extending from the distal to the mouth end, the body defining a device cavity to removably receive the article at the mouth end, and a heater to heat the element when the article is received within the device cavity, and to externally heat the article when received within the device.

A smoking article with a reduced tobacco smell and a method of manufacturing the same are provided. The smoking article according to some embodiments of the present disclosure may include a smoking material portion, which includes a tobacco material, and a filter portion, wherein the tobacco material may include a material formed by processing tobacco leaves whose nicotine content is 0.5 wt % or lower. In this case, the nicotine component and nitrogen compounds, which are major causes of a tobacco smell, are reduced from tobacco smoke, and thus a tobacco smell of smoke generated during smoking can be significantly reduced.

An aerosol-generating article is provided, including: a rod of aerosol-generating substrate having a length of between 8 millimetres and 16 millimetres and a resistance-to-draw (RTD) of between 4 millimetres H.sub.2O and 10 millimetres H.sub.2O; a downstream section provided downstream of the rod of aerosol-generating substrate, the downstream section including at least one hollow tubular segment; and an upstream element provided upstream of the rod of aerosol-generating substrate and abutting an upstream end of the rod of aerosol-generating substrate, the upstream element having a length of between 2 millimetres and 8 millimetres and being formed of a hollow tubular segment defining a longitudinal cavity providing an unrestricted flow channel.

The invention discloses a variable-ventilation filter tip and a cigarette. The filter tip includes a filter element and a coating layer. The coating layer wraps the filter element. The filter element includes a smoke inlet end and a smoke release end. A phase-change ventilation area and a non-phase-change ventilation area are arranged on the coating layer, a plurality of first ventilation holes are arranged in the phase-change ventilation area, and a plurality of second ventilation holes are arranged in the non-phase-change ventilation area. Outside air penetrates through the coating layer through the first ventilation holes and the second ventilation holes to enter a part of the filter element. A part in the filter element close to the smoke inlet end is provided with a starch tube. A phase-change material is filled in the first ventilation hole. A phase-change temperature of the phase-change material ranges from 45° C. to 60° C.

The non-combustible tobacco vaping insert includes a filter having a first diameter, and a non-combustible tobacco element with a first end contacting the filter. At least one first portion of the tobacco element has a second diameter that is smaller than the first diameter of the filter. The cartridge includes a heater configured to vaporize a pre-vapor formulation that is communicated to the heater by a wick. The insert is positioned in at least a portion of an air passage within cartridge, where the insert is configured to allow vapor that is generated by the heater to pass through the insert prior to being discharged from the cartridge.

The invention provides a heat-not-burn cigarette product. The heat-not-burn cigarette product of the invention includes a cigarette product and a heater in matched use with the cigarette product. A sucking resistance when the cigarette product and the heater in matched use with the cigarette product are used together is P.sub.1, and a sucking resistance of the cigarette product is P.sub.2, wherein a ratio of P.sub.2/P.sub.1 is greater than or equal to 50%.
