HERB® pipe has an innovative filter which contains over 10 plant enzymes and herbs (primrose, licorice green tea etc.) to collect and reduce the hazardous substances in smoke.
Simultaneously contains mikrochalazia (microsilica) which spreads specially fabricated fibers and externally surrounding the filter thereby entrapping the collection of harmful substances into the filter without allowing them to reach the smoker's mouth. Also the construction of the filter helps to destroy free radicals. Thereby absorb the tar and nicotine, without any changes the taste of the cigarette.

Each filter is effective for about 15 to 20 cigarettes depending on the tar and nicotine content percentages of each cigarette. Once the filter is in place you can throw it away and replace it with the next keeping the pipe for a long time.
