Odor control question

I have two questions. THe first one is where can i buy a charcoal canister that will eliminate odors? The second question is do they require anything else or do u just hang it from the ceiling

some one help me out. I c everyone reading about a guy thinkin sugar is growing on his plants and everyone responds to him but no one will respond to a serious question/problem that i have.

go check out ebay and if you get a shelf modle you can just leave it there
