Tobacco filter Activated carbon in tobacco filters

Activated carbon is an established filter material in the tobacco industry. In cigarette and pipe filters, it adsorbs gaseous components of tobacco smoke - including volatile organic compounds, aldehydes and other gas phase components - and thus contributes to changing the properties of the smoke. In contrast to acetate filter materials, activated carbon primarily acts on the gas phase of the smoke and not on the particle phase.

For use in tobacco filters, granulated activated carbons with a defined particle size, low dust content and reproducible adsorption performance are required. The particle fraction must be selected in such a way that it can be introduced evenly into the filter structure and generates the required flow resistance without impairing the filter mechanics.

Silcarbon supplies activated carbon grades that are tailored to the specific requirements of the tobacco industry - with defined particle size distributions, controlled activity values and stable delivery specifications for series use in industrial filter production systems.

Cigarette filter

In multi-component cigarette filters, activated carbon granules are used as a middle layer between two acetate filter elements. The activated carbon selectively adsorbs gaseous smoke components from the filter stream without completely eliminating the characteristic taste. The particle size and activity of the carbon are key factors determining the filter performance.

Pipe filter

Among pipe smokers, activated carbon filters are commonly used as replaceable inserts in pipe bowls. These compact filter units contain activated carbon, which absorbs moisture, tar, and gaseous compounds from the smoke stream. The requirements for particle size and dimensional stability differ from those in industrial filter production.

Quality requirements

The use of activated carbon in tobacco filters imposes specific requirements: narrow particle size distributions, low dust content, defined activity levels, and purity specifications are essential for trouble-free use in filter production. Silcarbon provides product specifications and test certificates that meet these requirements. Contact us for product-specific advice.
