Tobacco smoke filters

The subject of the innovation are filters. for tobacco smoke caused by the Use of metal foils to form the active filter surfaces to cool the smoke, thereby precipitating the contained therein harmful substances are reached »

The! Filters according to the innovation can be used as! Filter mouthpieces use for cigarettes or cigars or as pilter cartridges for tobacco pipes, "or cigar or cigarette holders ·

It is known to use filters made of paper, in particular crepe paper ¹ DZYi ₀ fibrous materials of the most varied types, for filtering TaDak smoke. These materials have the disadvantage that their heat conduction is poor, so that Taeim's passage of TalDa smoke. The temperature of the tobacco smoke is scarcely lowered by such filters. As a result, a relatively large proportion of the harmful substances in the breath in a gaseous state and oassierii in this form pass through the filter.

It is also already known that the Teuperc.; - υτ. ^ It smoke through it diminish that the same passed through metal filings or is guided along sheet metal strips. The disadvantage of such F114

The main reason is that their production is uneconomical, which in turn does not permit practical use. The metal strips can be used as filters for tobacco pipes, but are used as filters not at all for cigars and cigarettes "braunhoar.
