HElp me find a fan please

Sup everyone i am trying to get a small 1 to 2 lowryder growbox going and was wondering if anyone knows a site to get small extractor fans to hook up to a carbon filter for around 20 dollars thx.

depends what size ur area is and how much air flow u want to be pulling out.

around 3 by 3 by 4

use an old pc fan...............hook it up to a cheapy carbon filter....theres a thread in the DIY on the cheap 5 dollar carbon filter...it should work for your little box.....although you may need to refurbish it every 3-4 days.... I tried it. It works....but it quits... you gotta keep "crushing" the carbon to help it "scrub".....try it... heres the thread
Easy to Build DIY Carbon Filter

i have a 4 inch hole carbon filter i got from hydro store for 30 bucks lasts months i just ned a fan for it and where i would get a quiet computer fan for it that plugs into outlet

um.... well find a PC Trash dump....keep your eyes out...people are chunking old PC towers out everywhere...Most of the old PC's fans are still good.....just take the tower cover off a PC, and rip the hard drive fan out....you can re-wire the fan to an old cell phone adapter....Take the old Cell phone charger/walkman and snip the( part that actually plugs into the phone) and cut it off. You want the FAT part that actually plugs into the wall....strip the wires from both parts....RE wire them together...plug in the ole phone jack and you have a working fan....Now,.............. next time you go to Wall mart... buy a can of "Activated Charcoal" from the pet department....and while youre there...get a Scotchbrite pad.....and some duct tape....call me back.. I gotta go...
