These are very effective 9 mm filters that fit VAUEN tobacco pipes.

For the sake of the environment, the filters are made with hygienically white paper bleached without chlorine.

Pipe connoiseurs appreciate the extraction of large amounts of nicotine, moisture, tar and other pollutants from the smoke.

The surface of the active carbon of a filter is almost as large as two tennis courts.

The taste and thus the aroma of the tobacco are not affected.

You can recognize the filter Dr. Perl junior by the red packaging and by the blue cap.

Tip: Replace the filter after each use.

The cavity of the plastic cap creates more space for the activated carbon. More activated carbon means better filtration capacity.

Through many years of research, a particularly highly activated carbon of finest quality was developed for exclusive use for VAUEN.

Due to a special treatment, the active carbon gets countless pores with different sizes. The filtration is enhanced by the large number of pores. The most favorable degree between small and large pores guarantees the highest retention of the nicotine and tar particles.

The smoke from the tobacco chamber cannot directly reach the mouth.

A look through the microscope shows the “craters, caverns, and channels” of each activated carbon piece which now have to be passed. A high level of nicotine and tar is retained there.

The longer the “deviations” of the tobacco smoke through the labyrinth of activated carbon, the greater the filter effect. The surface of all activated carbon pores in one single Dr. Perl junior filter approximately corresponds to the dimensions of two tennis courts. So it's no wonder that Dr. Perl junior achieves an outstanding performance in the matter of filtration.

To be able to guarantee this we recommend to replace the filter after each pipe filling. Please insert the filter in the pipe like this, so that the blue cap shows towards the mouthpiece.

The optimum draw resistance – not too high and not too low – is guaranteed by the exact size of activated carbon pieces.

The white, non-chlorine bleached filter paper and the white filter cap retain unwanted humidity due to their enormous absorbency.

The multitude of holes in the caps provides an equal distribution of the incoming smoke among the activated carbon bits and at the same time the best filtering benefit from carbon and paper.

The use of dustfree activated carbon protects from disturbing particles in the mouth and prevents unwanted changes of taste.

Continuous quality checks guarantee constantly high filtration values.

It is precisely in little things that the power of innovation can be seen. In 1921 VAUEN was 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. This was a convincing innovation which in the course of time moved virtually all pipe manufacturers to convert their filter bores to 9 mm.

VAUEN set 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 has also resulted in a continual change in smoking habits outside Germany as well. Dr. Perl Junior sells more than any other 9 mm activated charcoal filter in the world.

For an optimal fitting in the pipe, VAUEN pipes have the "Conex” system where the special design of the mouthpiece plug makes sure that unfiltered smoke does not penetrate between the filter and the plug. Simply press the filter lightly into the plug.

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. With yet another forward-looking invention, the VAUEN company meets the high demands of true pipe enthusiasts.
