These systems are very expensive from a preparation standpoint, and these systems have significant damage in that the chamber stability is insufficient with respect to compression during smoking. Another possible solution is a double filter structure in which small amounts of activated carbon are interspersed within the tobacco side filter components. These structures have only limited and insufficient gas phase reduction in many possible applications. Flavor (smokers describe it as charcoal flavor)

It is shown that it depends on Combinations B, D and F of retention and permeability shown in Table 1 have proven to be particularly preferred. Combinations A, C and E are known cigarettes, which were modified by combinations B, D and F of the present invention.

よって示された。It should be noted that as the condensate and nicotine values decrease, the retention index of a single filter segment increases. At the same time, in order to achieve at least the same scent quality of tobacco, it is necessary to increase the porosity of the cigarette paper of the comparative cigarette in question and at the same time reduce the filter ventilation. Here, one basis for the relative improvement in scent quality is the particle size distribution of the mainstream smoke, which is crucial by different flow rates and therefore different temperatures at which tobacco stops burning. Affected by Tests have shown that when the test and comparative cigarettes are matched in terms of flow, a so-called loss of charcoal flavor and aroma quality occurs.

It can be used in the mouth filter part: for example, the coaxial structure of the mouth filter part offers the possibility of optimally setting the desired holding and the desired opening suction resistance of the cigarette simultaneously and independently of one another in a known manner. .
