  • Table 1 below presents the experimental results observed in laboratory tests of the reduction in the ventilation standard deviation and of the reduction of carbon monoxide content obtained with the use of smoking articles of the present invention compared to commercial products with both high and low ventilation levels.
  • mouth end represents the distance between the extremity of the filter closest to the smoker's mouth and the ventilation perforation line.
  • TAR is the term used to describe the total substances present in the smoke excluding water and nicotine. Inhalations represent the number of times the cigarette is smoked by the smoking machine.
  • the measurement of the ventilation consists in the application of a vacuum to the cigarette extremity containing the filter, generating an airflow of 17.5 mL/s through the cigarette (tobacco rod+ventilation).
  • the airflow that passes through the cigarette tip and the tobacco rod are measured using a low-pressure transducer and these individual measurements of the cigarette are performed by adequately isolating the areas with coils lined with a latex glove.
  • the result of ventilation is expressed as the total % of air that passes through the tobacco rod and the ventilation.
  • Alternatives 135305 and 135304 provide the ventilation openings positioned over the filtering element and alternatives 135302 and 135303 provide the ventilation openings over the space between the filtering element and the tobacco rod. As can be seen, the lowest ventilation standard deviation and variation coefficient was obtained for alternatives 135302 and 135303.
