where can I source some activated carbon for a project like this?

I just want to make a little fume extractor, and every web search pulls up all commercial stuff ack

I am not sure what project you are referring to, but have you seen the improvised gas mask?

From the comments on that project:

you could also get activated charcoal from your pet shop, its used in the water filters, you may need to smash it a bit to make it pack in closer to your filter. I would also recommend, sealing off your filter when not in use, it will keep absorbing contaminants in the air just sitting around. Interesting idea....

Thanks for your answers guys... The project us a fume extractor, for soldering.. For $9.00 I actually went to Graingers (whoops, forgot I have account there!) , who sell 24inch square sheets of it for air filtering!!! I was happily surprised. I am sure I will have to squeeze it together to filter more completely Thanks!! I love this Instructables site!!!!

You should be able to get it from a pet store, since it's used with aquariums. If not, smash open a Brita (or other brand) water filter.
