I was about to ask the same question OnlineSimRacer. I see these in everyone's pictures, but cant find a single thread explaining how to use them. I know what they are for, just not where it needs to go, how it needs to go there, or well, anything. :/ I plan to make one of these tomorrow though.
Also waiting for an answer on the below posts. As I am currently doing a closet grow.

awesome. very helpful
This thing saved me quite an embarrassment.
I had set this up in my stealth growbox about 2 weeks into the grow, as it started to smell. My growbox is an old entertainment center with a plywood door attatched. It is located in my finished basement where my water heater, water pump and water softener is in its own room. i am growing 3 plants in there. I used a 4 inch inline fan reducing to a 3 inch with the filter wrapped around that. pretty much like the intructions. about a week went by and I still could smell the plants. I kind of let it go for awhile as no one was really going down there, it's just my wife and me. ( my wife doesn't even know about it, it is going to be a surprise)
anyways, my parents were coming to visit for a weekend, and since my mother has an unnatural sense of smell, I thought I should fix it. well, the problem turned out to be that the inline fan was pushing TOO MUCH air, so it wasn't filering efficiently. the day my parents were to show up, I went out and bought more carbon filter material and wrapped it over the original filter. essentially doubling the carbon filter.
about 3 hours of cleaning, and 3 hours before my parents were to show up, my WATER HEATER broke no hot water. I had to call a repairman, who showed up about an hour later. I went down to check the growroom smell.
The repairman was 4 feet from my growbox. not a smell. Parents here all weekend. not a smell.
so word to the wise. if you are using an inline duct fan, make sure it doesn't push too much air. It will reduce the effectiveness as it filters the air being pushed through it.
What was the free air cfm of the fan you were using? Curious. I dont have a speed control yet for my fan and wondering if I should grab one.
does anyone know if activated aquarium carbon will work the same?
As far as I know, it should. Everytime I see someone ask where to get activated carbon, people tell them to look in the aquarium section.
sweet man thanks for posting, this might be of some use
genius, what a good idea, always remember any carbon material is basicallly spent after 6 months or so.
With only one chance at life one should live it up
