Looking for carbon filter plans,pls help

anyone with plans on building a cheap carbon filter,please help.i need one badly,plants really starting to stink the place up,growing in shower stall and bathroom fan doesnt quite cut it.any wooden designs?.iv got lotsa wood,screen, and charcoal.also,anyideas on weather or not those 4 or 6 inch inline fans from home depot or princess auto work? says they push 280cfm but only cost $28.thnx for any help.

for about a 100 bucks or less you can buy one of those paper carbon filters
they are light weight and cheap
if thats to expensive for you
i would try using a barrel and inlaying it with steel mesh then put the carbon in it and pack it down. keep doing this till its basically full then seal the top and run the fan into it. cut a hole in the bottom so the air can go thru the charcoal and out =)
gl man hope it helps

thnx kingteg,thats got me thinkin.i guess pushing air through carbon opposed to pulling it through,shouldnt make a difference?

yes it does make a difference.u want the filter and fan to suck the odor out of the room, so u put filter on the vaccum side of the fan so the fan is sucking the air in the room threw the filter with a piece of ducting on the other side of the fan exhausting it out.

i just blow the air into the carbon filter than out
it doesnt really matter it can work both ways =) just depends what you prefer

Im still needing one also.........................................................
