Very nice. This is why i logged on tonight. Thanks, Wolfman Zen! +rep

Just had to add to this guys thread, I've built the identical filter he outlined and panty hose 100% don't work. They clog with dust repeatedly and your airflow becomes nil and temps start climbing. I rebuilt them and used some window screen I had laying around, works much better! If you're thinking of building these skip the panty hose from the start!

This is great im going to make a slightly bigger one thank you so much

nice nice stay high!

Nice DIY!

awesome filter. +rep

very professional lookin filter man... + rep

Works great, masking all odors; although it's probably overkill as I already have an ONA block in there. It saved my ass though as it completely killed the light leaking I had from the exhaust of my PC fans. Thanks and +rep for the great tutorial!

Great job and +Rep!

anyone have ideas for the size of an xbox fan?

I want to attach my own design of this to the back of my pc grow case, would a 120mm pc exhaust fan successfully push air through it?

you want to PULL the air through it, not push

after deciding activated carbon is kinda expensive, a quick search turned up this:

seems easy enough...

fuck it ill buy its to much work i can get it for 25 buck and i wont run out for a long time it comes in a Liter i think or more

I just put this together and hooked it up to my 120mm PC fan cooling a waist high dresser/cab. All the materials cost me roughly $25. The hardest part was hooking it up to my fan due to the placement of the fan in my cab.

One thing I noticed is that it's hard to find the smaller pencil cup in stores, well at least here in Hawaii. Even online through Amazon I could only find the larger cup so I went and got this pencil cup http://www.officedepot.com/a/produc...Metro-Mesh-Jumbo/?cm_cat=2000000353#reviewTab I think mine measured about 4" diameter and rougly 6" tall. It was not curved like the one in the original post. I then took 3" or 2" (fogot) net pots I had lying around and glued them together at the top - cut out one of the "bottoms" and I made the inner "cup" as pictured.

Then I just followed directions as stated. The carbon layer is much thicker than the original post however it's still a very clean and sleek look and build to it. Even with the thicker carbon filter the fan is still pulling air through it strong - Not sure the filter silenced the fan much in reality which was what I was hoping since it's right next to my bed.

The cup was slightly touching the fan blades so I made a cardboard "frame" for the opening that connects to the fan for a small spacer - that did the trick! Then used black duct tape to secure and seal the slight openings around the filter meeting the fan. My PC fan is rated at only 74cfm, so right now lights are off and it's PM but I'm highly confident that during the day temps should keep to roughly roughly 81-85 degrees F. Oh yeah, I only run a 100w blackstar UFO on two SCROG plants right now so heat from lights is negligible.

Plants haven't even started budding yet (2 weeks into 12/12) but with the positive reviews of odors begone plus a thicker layer of carbon I am confident the filter shall perform as advertised.

Great tutorial, thanks! I have a problem though - my filter isn't filtering the smell! I've bought activated carbon for aquariums and I think it should work. Maybe the problem is in PC fan which is rated 42CFM (8cm diameter)? Here is a sketch of my setup: You can see I have two fans pulling the air out. Where do you think could be the problem?
