While working on solving a ventilation problem, I remembered an old DIY-carbon filter I saw a long-ass time ago on OG or somewhere. I wish I could give credit to whom it is due, but I don't have a clue where the original article was.
Anyway, all I really needed was a piece of 4" ducting to run into a tent, but I had some old stuff laying around and decided to see how well the ghetto scrubber worked. The ladies are in full bloom, and the ozone wasn't quite kicking all the stank out.
Anyway - all you really need is:
-a piece of chicken wire
-some kind of 4" solid duct tube (I prefer the twisty type as you can adjust them to fit tricky places)
-one of the odor-control carbon furnace filters you can get at local hardware stores/Wal-Mart/wherever
-a bunch of zip ties of various sizes (remember - you can always make them longer by hooking multiple ties together...)
-some big-girl pantyhose (luckily, I have a girlfriend with a lil' extra booty)
Image 1 shows the chicken wire rolled up and shoved in the tube. Nothing is holding it in except its desire to unfurl itself within the tube. I put some zip ties at the top and middle of the chicken wire to hold it together in a tube. Note that I have the top of the wire folded in where the sharp cut wires are. If you situate the wire right, you should be able to point most of the sharp wires inward so they don't catch on anything.
Image 2 shows the top of a rubbermaid container I've cut down to cover the top of the wire cage. I poke four holes in it and zip tie it to the top of the cage, as in image 3. Try to get all the cut off edges of the ties pointing downward or inward to avoid issues with snagging...not that big of a deal, but you'll save some poked fingers in a moment.
Image 4 & 5 show the next step - cutting out a sheet of the carbon/baking powder filter that is long enough to wrap around the cage with maybe an inch of overlap, and tall enough to touch above the plastic top and below the bottom of the cage at the same time...zip tie it on, and try to make sure there's not too big of a gap between where the filter overlays itself or the air will escape through the gap unfiltered. You might want to put a tiny piece of duct tap over the little holes in the plastic for the zip ties
Image 6 - You need about 1/3rd of a leg of your big girl pantyhose rolled up like a condom. Just put it on your arm like a glove and neatly role it off all the way, until it is a ring with the middle relatively taught. Stretch that ring over the plastic end of the fixture and roll it down a bit...this will push the little bit of overhanging filter at the top down and force the bit of air around the gaps at the top through a filter.
Voila - you should have something that looks like image 7. It actually seems to do a pretty good job of knocking out odor, but I imagine it will run out within a few weeks. You can easily replace the filter by taking the pantyhose off the top, cutting the zipties, wrapping a new filter around (you can probably make 2-3 of these out of a single large filter), and replacing the pantyhose condom at the top.
Match it up with a Stanley Blower Fan for like $35 bucks and mod it like this dude...http://www.icmag.com/ic/showthread.php?t=29341...and you probably have enough suction to vent and odor control a small tent setup...
Good luck!
