Are you making your own carbon filter? If so, you can find activated charcoal, ideally suited for your needs, on Ebay. All "carbon" filters use activated charcoal.

Here's an example:

If you don't want to go through the hassle of building your own, you can buy one for almost the same cost. A good filter that will last you about 18 months of continual use, with 4" intakes and exaust vents will cost you about $135 at your local hydro store. Effective too.
