DIY CARBON FILTER ROUND 2
DIY- Inexpensive odour neutraliser

I've never build the Round 2 carbon filter, but I've build a scrubber like the one in the link smpaz gave you, as well as the second one I listed here. They both work great, but I prefer not to mask odors... so I stick with the filter. Never given me any problems, but the activated carbon may need to be changed more frequently than a larger, prefabricated one. I'm now hearing some people say that theirs has been going strong for several years. I'm lucky to make it two years before I have to change out the carbon. Still, it's not a difficult process.
