Tune activated carbon filter systems:
-improve the taste of the smoke
-reduce the amount of tar that reaches your lungs
-keep your pipe clean longer
-make harsh blends taste smoother
-make it easier to smoke pure.
By the way, unlike traditional activated carbon filters, Tune activated carbon filters have a special cap on the end that won't get clogged and won't allow sticky tar to get into your mouth, even if you use one in a joint!tip-tube, Tiptube, Actitube
