Would I be able to use 2 carbon filters on my bong and still have it purify the smoke without taking the THC because I have an ash catcher and if what I'm thinking is correct then I can make my bong the smoothest thing in the world by filtering the smoke through water twice and two carbon filters
The greater surface area your piece, the more chance for resin to stick to the walls. Porous carbon creates an extremely large surface area. You will be extracting more and more thc with every add-on.
