I like the basic concept, but I have a couple ideas for using the bags that may help with airflow. Either making an intake box or using a larger pre-made vent that can connect to flexible ducting. If you have an intake box then the bags could lie flat on top an opening sized smaller then the bags. The bigger the box, the more bags could be layed across the opening (supported with some sort of grid or screen.) cut a hole in the side to pull air through duct to fan and out exhaust. This would really help with resistance. spreading the intake over a larger area. But, then again, maybe it would pass through the thinner layer (as opposed to "stuffing in the duct" idea) too fast and reduce effectiveness? Just thinking out loud sorta... Hope that makes sense. I know pictures are best, but they only exist in my head at the moment. If I get around to trying I'll post pics.

great idea man, thanks. do they only work if they're being used with a grow box? or can it be used for weed growing out in the open?
Stinky air has to move through the carbon for it to work. Though there may be some small effect just with the stagnant air's contact of the outside surfaces, I wouldn't expect a big difference in smell just from tossing the bags in a box.

i was only able to find the (Scott Scrub Cloths) http://www.amazon.com/Scott-11-14-5-Scrub-Cloths/dp/B002CRZYZU
Will this work? i am able to blow threw it. so im thinking it will. and im un sure of how much carbon to put into the bag. im about to start maken it right now so faster responds the better
thank you guys. + rep to who ever responds. its going to be going onto 6inch exhaust fan... im starten to fear its to thick. anyone? maybe if i poked abunch of holes all over after its all put together?

Thats a good question on te computer fans,im not a big fan of using comp fans though,their build quality is questionable for our purposes & in no cases are they meant to be ran in conjunction with any type filter or anything that would restrict air flow.
Another thing ive noticed about computer fans,this came to me when i was messing with a regular window fan in my bedroom,my wqife bought me a new fan for the room,i put it in the window & couldnt feel shit & it was on high too,i got to looking at the slim line design & the twist to the fan blades was minimul in order to keep the slim profile,this resulted in very little air being moved more than a few feet past the fan,my old fan had a very deep twist to the blade & could be felt from all the way across our bedroom which is 14ft.
Every computer fan ive ever used had that same very slight twist to the blade,im not sure they are fit to move air in a grow op unless its a very small enclosed cabinet,not because of lack of cfm but lack of their ability to throw air long distance,something they were nerver designed to do from the start.
FYI you can buy 4inch,6 inch & 8 inch inline duct fans at home depot for $20 for the 4 inch models,$30 for the 6 inch & $40 for the 8 inch models,i know for a fact that these type fans move asir long distance because i use them & the filters will work with the inline fans.
Hey how loud are these. I plan on getting 1 or 2 to exhaust my room.

there not to loud i have one running right behind me. its quiter then my window ac units fan. got alittle hum to it.
Here goes attempt 2 at maken one of these filters. i wasnt able to find the same scotch brite that was used in the first post. but i did find the scotch brite kitchen & general purpose wipes. they have alittle amonia smell to the but i dont think it will matter just help on killing the oder.
And i most definitly think this wont be to air restrictive i can see right threw it np and blow threw it np. so here goes attempt to..
wall im sowing this thing up could someone please let me know how much and how small of carbon chunks i should be usen? The carbon i have now is 1/8 in diameter so maybe it came small enough. but how much should i be usen in a single pouch for a 6inch duct fan?. i dont want to put to much to the point where its restrictive but i dont want to put to little to the point where its leaking smell out. so i kinda gotta get this all squared away before i make that final stich. i can always reopen it but then its not as strong.

This thread is dead. does Panhead not hang out in RIU anymore?
i guess ima just ahead and put the full 9 oz of carbon into the pouch.
im really at a loss how to keep the carbon from just falling to the bottom of the bag. i apply clamp and made the bag and filled it with the entire 9oz thing are carbon. i throw it on my fan and bam the carbon just piles up on the bottom of the bag. and the entire top is just the bag free for air to go threw un cleaned

I just made one of these using ducting material, the scotch brite cloths and a bunch of duct tape. I stuck mine at the end of my flexible ducting because i already have a big carbon scrubber on the front.
Anyways, is anyone else concerned that these could be a possible fire hazard? Considering that youre restricting hot air while using cloth material and carbon. Activated Carbon is not insanly flammable, but it will catch.
Who's been using these for a long period of time?

Are these filters still breathable?
I mean, can I have air flow through without a fan pushing it? For instance, have a grow box, sealed except for large squares covered with these filters. Would the plant suffocate? If I had a fan inside the box, to circulate air, would that help?
My issue is with the size of running an external exhaust.

yeah you get 1 small one for $4
not so good a idea, making them you can put alot more carbon in em and for much less cost. here they are at walmart

check this out, I made this with the filter mentioned here and I got EXCELLENT RESULTS, hands down.
Formerly my DTY hydro setup but since the one plant left went to a 5gal bucket there were already holes cut so all I had to do was add a fan and make some filters.
10 Gal Tub $3.50 Walmart
Fan $7 Walmart (got it on sale end of last summer)
Handi wipes $1.47 for a couple, this used 2 or 3
Active Carbon $6.47 walmart (used about 2/3 of it)
Pretty damn cheap and it has defeated the smell in my room 100%.
It doesnt blow much air out or suck it in, but it does work all on it's own, Im very much impressed.
Under $20 I bet I saved $140 there atleast.
God I love good RIU and good ol Walmart.

This is PERFECT for what I'm doing (I'm already using a bucket just like that!).
Is that fan blowing in, then air escapes through the filters?
Edit.....wait wait wait wait....you mean, you DON'T have to have the plant IN it? I can just make a bucket that is esentially an air filter, had have it running in the room I have my grow bucket? That would be fucking awesome!

the fan is blowing out, sucks though the carbon filters and blows out of the box, cept it more like blows it from the sides of the fan, really odd, Im gonna make a baffle and try and up the efficiency of it. But yeah it works like a wet dream, should be stinky but it's just wet LOL. Im not gonna need a inline filter period, ill build a bigger one of these outta a 22gal tub i have no other use for, Im gonna get new fans for it so ill post it prob next week.

Are you working on reinventing the wheel too? jk Great stuff panhead +rep
Great stuff panhead +repATTENTION TO EVERYBODY ! ! !
CARBON FILTERS WORK ONLY UNDER HIGH PRESSURE OF AIR.
This meens that if you put a low power fan
(like a PC fan) YOU DO NONTHING!
Also if the whole system is not well insulated (airproof from the entrance of the filter to the end of the fan) YOU DO NOTHING.
I used a comersial filter with a PC fan for my last crop and all the smell was going outside completely unfiltered!
I noticed that after 3 months...
