Easy to Build DIY Carbon Filter

:joint:

Thank you MightyBuddah for researching and posting that information. It was precise and informative. I know I'm a little over four years late to the forum. But, you have save me time and $ with your research! Thanks again!
 
Wow very informative thank you ...Well I am new I like to learn about removing room odor.I under stand carbon filters help. Do I have to extract the air out of the room or can I circulate the air. I am not to worried about heat because I be using LEDs.What are some of the basic for removing room odor?
 
You want the air to be exchanged/extracted thru the room because the plants need fresh air to be healthy. Place an intake hole w/ a fan pulling air in the bottom of one end of the room for your intake, and place an output hole w a fan blowing out in the top of the other end of the room. Place the carbon filter described in this thread between the wall's "output hole" and the fan like shown in the first post:513_p5707.jpgView attachment 1776032

The reason to place the intake and out put holes at the bottom of one end and top the other, respectively, is because heat rises and cool air is dense and"sinks" so this set-up allows cool air to be sucked in and the hot air to be exhausted.
 
how strong does the fan have to be? im afraid that my fan wont push the air through the carbon
 
MightyBuddha thanks for sharing this with everyone. I will definetly be using this design once my room is complete. Nice and simple and easily customized to suit ones needs. +rep.
 
Just so I can be clear, I need the air to come through the carbon filter, then be vented out of the grow area via attached fan, correct?
 
all of you, how big is the room you trying to scrub with this, i have a 6" vortex and 36" carbonfilter to do the job

I can't take credit for this it has been ripped from another site but it is worthy of posting. I built one about double the length of the one below and found it to be very effective. I also attached it directly to a bathroom fan unit so it is inside of the grow room not hooked to the exhaust.

Im sure this works well but roll of screen is about $8 filter is about $20 both ends are about $15 for end cap and reducer. and about $5 if you dont have duct tape already. if you can afford the $40-50 for this go the extra $20 and get a real one. HTGsupply.com has about cheapest ive seen.
