A Carbon Filter is an attaachment sold for Glass on Glass bongs. It is composed a male joint at the bottom, a large spherical chamer to fill with Carbon, with a glasss screen preventing any from falling out, and a female joint on top. A Carbon filter makes even the shittiest china bud taste smokeable. And the taste is undescribable if your smokling a good strain in it! As an added bonus, nearly all the tar is filtered out of the hit and your bong will never get dirty.
DUDE! This Carbon Filter is fucking AWESOME! Where can I get one?
