Cap | Activated carbon adapter | 18.8 mm

bong attachment with a 18.8 mm joint size. This adapter will let you smell even cleaner smoke, filter it out and give your lungs an explosion of freshness. Of course, before the whole process, you have to throw activated carbon into the cap, without it. The bong cap is adapted to the 18.8 mm ground joint size bong. Activated carbon in combination with water filtration used in bong creates a perfect synergy. The smoke is free of even more tar and is softer on the throat.
