    Great post. Do you use it like a scrubber in the room or is the filter out side of the grow room?

    You can use it both ways the room I originally used it in was vented so I just pulled the air through the filter and out in to the atmosphere. the exhaust was virtually odorless. The air flow through the filter was good, I noticed minimal temp rise with the filter attached. In a sealed room you could use it as a scrubber.

    the filter material is just some bulk filter material I picked up at the local hardware store. comes in a big roll you just cut off however much you need. I've also seen it in different colors but it works great in a variety of applications. Just have to be creative.

    You could build one with what ever materials you have. 6" pvc pipe would work, however in a 5 gal bucket application you would greatly reduce the amount of carbon the contaminated air would touch in a single pass, thus reducing the effectiveness of the filter. if you were to use it as a scrubber where the air would pass over the carbon multiple time, then this would not be a big issue. On the the other hand there is no law that says it has to be a 5gal bucket. You could theoretically use a number of containers ranging from a rubbermaid tote to a 55gal drum, just uses what ever you need to fit your needs. The building concept would be the same just modify the design a bit.

    re: DIY High Flow Carbon Filter

    where does the fan go on this , i currently have a carbon filter and 4" fan inside my tent with a flexible line hooked to it and running out of my tent . does the filter you built go on the end of that flexible hose ? do i need a second fan before the filter you built ?

    Re: DIY High Flow Carbon Filter

    SunGod I really do like your Filter / scrubber , I know it will be very effective !!

    As it has about 4 inches of carbon

    Those common longish hydroponic carbon filters used to use 2 inches of carbon now most are using just 1 inch

    Like you I used the Pellets , I bought 25lbs of them from eBay for $50

    Before I bought the Carbon I looked into it and found that the Carbon pellets work the best and last twice as long as other types.


    I made this one last week from a mesh waste paper basket and a roll of wire with 25lbs of carbon pellets set 2 inches in thickness.



    It has a 6 inch 12v 170CFM axial fan mounted in its top , I still need to get the pre filter
