It is precisely in little things that the power of innovation can be seen. In 1921 VAUEN is one of the first manufacturers to introduce a paper filter for its pipes. VAUEN improves and develops the pipe-filter further and in 1934 presents a world novelty, the Dr. Perl junior activated charcoal filter. A convincing innovation which in the course of time moves virtually all pipe manufacturers to convert their filter bores to 9 mm.

VAUEN sets a far-reaching trend in motion with this invention. More than 95% of all German pipe-lovers today smoke with an activated charcoal filter. Top performance in terms of filtration and the dry cool pleasure of smoking with a Dr. Perl junior filter is also resulting in a continual change in smoking habits outside Germany as well and it sells more than any other 9 mm activated charcoal filter in the world.

In order to maximize filtration performance VAUEN has fitted all pipe models with the Conex system since 1968. The plug of the pipe is conical in the inside. The special design of the plug makes sure that unfiltered smoke does not pass through. Another forward-looking invention the VAUEN company which meets the high demands of true pipe enthusiasts.
