EDIT 2/23/11: I bought and used the odor absorbing gel, it smelled strongly for the first week, then tamed down, i don;'t notice the smell of my ABV as much, but i think the real key is i bought some aloha bags to keep my whip and stash in, they're zip-lock bags that are heavy duty. opening a window seems to be neccessary. i brought in my inline fan and charcoal canister and don't know that they really help that much, but i'm not venting to outside.

i remember hearing about Ona Gel, but it's pricey, so someone else recommended this stuff at Lowes...
NATURAL MAGIC 14-Oz. Odor Absorber Gel Citrus
Item #: 73369 | Model #: 9066C-12
$3.98
what works for me is not doing it before the family gets home, and following a strict regimen of keeping both the bedroom and bathroom doors closed before i open anything, and spray afterwards, cross-ventilation even for just 20 minutes...otherwise i get an earfull from my teen daughter ("IT SMELLS LIKE WEED UP HERE!")
it's often the smell from my shirt, or if i left my whip out (bought a new mini-whip for my Hakko!) or left ABV uncovered in the bathroom, so eyedrops, changing my shirt, brushing my teeth, then mouthwash...or well, I need to give the walls in the bathroom a once over with Spic'N'Span - you can smell it in the bathroom, but not strong. i'm a concerned citizen, and still i get the high hat around here. (hehe)
If you decide to just get a carbon filter, you could get by with a used inline Vortex 4" off Cragslist for $75, add a Home Depot $12 fan control to reduce the volume, sit that atop a new 12" carbon filter from a hydro shop for $75, build it into a book case that sits in front of your window...?
the piece of furniture would need to be as wide as the fan at some point, about a foot, swadle the motor in insulation and stuff it into a small box, maybe a cheap foam cooler, not from Walmart, lol, inside a plywood box, hang it under the lowest shelf of the bookshelf, use a metal duct to come up and go towards the window - cover that tube with three sides of a masonite box, paint it white, paint the shelves black, stack books and CD's in front of the workings, could be pretty stealth
if you can get up into the attic you could mount it up top - take over an existing air vent if you have to, just so it won't be visible, like in this picture where it's just above someone's tent:
or put a big old cabinet partially in front of your window so you can vent out it, hide the fan...and maybe grow some...
When I started vaping I'd read quite a bit, and the idea that it would only smell like incense fooled me into thinking that when I opened my stash it didn't smell...like years of experience had vanished, and i was the old man who's farts didn't smell anymore, hahaha
i like that pull-my-finger graphic!
