I found a way to filter any pipe to Perfection. It is simple and I believe superior than the 9mm filters that anyone can try at home. Cut a small portion of a tissue paper and roll them into tiny balls and drop the at the bottom. Ensure the draft hole is sealed. Then, pour small, activated character pellets until the tissue paper “disappears” or is fully covered. It eliminates dottle, and doesn’t allow any tobacco to pass through to the mouthpiece. Given that some don’t like filters or how they change the flavors, I also can not use 9mm filter or any other filters as they constrict the draw, and for some odd reason, make the tobacco flavors muted. At first, I didn’t notice this as I was smoking with filters, but as I got used to this new method, I completely understood why forum members despised filters. It does actually reduce flavor, due to the constriction of the airflow or the papers themselves, it is up to you to judge. But my method has worked for me, and I can use any pipes without any problems. At the end of every smoking session, I just dump everything and clean my pipe as usual.
Small tip: buy the big bags of activated charcoal pellets meant for fish tanks. This will save you loads instead of dumping 9mm filters charcoal into the pipe. But of course, if you want to try this method before committing, you can use the 9mm filters and dump the activated charcoal on top of the rolled tissue paper. I don’t know why no one thought of this as this method works flawlessly. The tissues absorbs excess moisture, and the activated charcoal completely rids of any harshness without the drawbacks of traditional filters.
