Activated carbon filters can be used to filter vodka of organic impurities. Since the activated carbon does not bind well to alcohols, the percentage of ethanol is not significantly affected, but the carbon will bind to and remove many organic impurities which can affect color, taste, and odor. Passing an organically impure vodka through an activated carbon filter 6-12 times (or through the same number of filters in one pass) will result in vodka with an identical alcohol content and significantly increased organic purity, as judged by odor and taste.
this was busted on mythbusters... the amount of carbon, filters and time it takes to make a bottom shelf vodk slightly better you were better off buying the top shelf... Grey Goose all the way!!!
