Due to its good filtration efficiency, it guarantees compliance with the legally prescribed maximum levels in tobacco smoke, withstands changes in humidity, is heat-resistant and very durable
The fibres (4) of the filter tow are arranged to have a particular curvature which is similar to the curvature of the filter shape where it meets the tobacco rod, and this allows the flow of the smoke stream to flow from the centre towards the outer edges of the filter (la), increasing the overall rate of filtration and the uniformity of filtration over the axial cross section compared with a filter in which the fibres have no such curvature
Notwithstanding the harmful impact of smoking and demerits involved, if we talk about pricing and comparison of it in different geographies then it is hard to ignore that the price of a pack of cigarette mentioned in the post is higher than what many earn in a day in this country
