I filter the smoke with my lungs.

I don't know about that activated carbon stuff, it seems like just another unnecessary accessory for ROOR owners to buy. I know activated carbon is really good for getting rid of stinky smells, when I used to have a saltwater fish tank I kept a can of that stuff next to the tank (it got kinda stinky sometimes) and it work great at curbing those smells.
