the "activated" of activated charcoal means charcoal that has been exposed to a chemical or process like described above which increases the effective surface area by some moderate percentage.. I understand that this may be critical in efficiency ratings of expensive fish tank setups but for getting dank odor out of the air I dont think the difference will be worth the cost. *I could be wrong..

I just ordered a charcoal filter and i have a bag of kingsford sitting here.. although I would highly reccomend you dont use the "match light" or "lighterfluid not req" versions since that would be.. stupid.

I have good ole hard as hell to light plain jane charcoal and Im going to bash it up.. wash it off in the bathtub.. then refill my filter with it.. which as I understand may not last as long as "activated" charcoal but should have the same effectiveness for maybe (Im hoping) at least half the life of activated.

If so it will be my new solution to odor control.. cuz activated is expensive!!
