Dream Vapor Carbon Filter Replacement

Some people swear by filtering their pipe or bong smoke through some sort of filter type.  One of the main types of filters in glass are Charcoal filters.  Activated carbon is made from many materials and used by  filter companies from Industrial to Consumer brands based on its’ ability to absorb chemicals and impurities from the environment.  Dream only uses a natural, organic coconut shell based carbon alternative after seeing some people resorting to using “dirty” or bituminous coal (the gross stuff that is non renewable and mined out of the ground)
