Inline carbon filter?

Is there any way i can have a carbon filter inside my ducting? I really dont want nothing sticking out of my box so this would be great! Any suggestions would be appreciated!

I saw one today built for inline when I was searching filters on yahoo I am not sure where though. Sorry but the best I can do is say I know it exists and someone online is selling it.

carbon filter goes inside the box with a fan sucking air thru it blowing scrubbed air out the grow space
