Re read this myself and am really thinking about getting one and thought I would bump it up encase others are looking at some different oder control options. I use a carben scrubber, but may try one of these out on my new set up. Seems like it would make it more convenient to seal a room because you wouldn't need to have to vent out smell and revent it in or use dampers and have to place a scrubber somewhere along with a fan, just have one of these , AC and C02 set up and your ready to role.
