Fill this active carbon filter 18.8 mm from Magic Glass with active charcoal, and filter carcinogens from your smoke, when you plug the downtube to it.
Active charcoal filters unedifying components out of the smoke and that way it's making the smoke smoother and less harmful.
Activated carbon can be found in our shop as well.
Activated carbon can be ordered here, too.
