I work in the chemical industry and we use CARBON filters to filter out unwanted purities in EVERYTHING, in size's from a pencil, to 500LB tray's located in the (smoke)stack, and it work's like a charm. How Carbon relate's to clothing, I have no idea, because clothing is not air tight, like most carbon filters are.

And with that being said, Carbon does need to be heated at extreme heat for a long amount of time to "re-activate it, it is such a difficult process in fact, that we just discard the "used" filters and replace them with new one's.
