Easy to Build DIY Carbon Filter

The pictures earlier have the scrubber half way built. The thing is a ring within a ring and I used chicken wire (the thick shit) and wrapped it in window screening and a thin sheet of activated carbon to extend the life of the carbon in the scrubber. This SOB works like it won the Olympics. It kicks absolute asss on anything on the market without a doubt. If you need serious odor control, this is the ticket.

So does this go out of the exhaust hole with a fan on the inside of the grow box blowing through it?

I was about to ask the same question OnlineSimRacer. I see these in everyone's pictures, but cant find a single thread explaining how to use them. I know what they are for, just not where it needs to go, how it needs to go there, or well, anything. :/ I plan to make one of these tomorrow though.





Also waiting for an answer on the below posts. As I am currently doing a closet grow.

I dont really have an 'exhaust' for my first grow. Just a closet grow, and I keep the door open a lot, though my plants are starting to smell a bit, and they're AK-47s (STRONG smell)... can I make a filter attach it to the front of a small fan and just have that in the closet? Plan the back of the fan towards the plants, so it sucks air through the back, into the filter, and back into the room/closet????

This thing saved me quite an embarrassment.

I had set this up in my stealth growbox about 2 weeks into the grow, as it started to smell. My growbox is an old entertainment center with a plywood door attatched. It is located in my finished basement where my water heater, water pump and water softener is in its own room. i am growing 3 plants in there. I used a 4 inch inline fan reducing to a 3 inch with the filter wrapped around that. pretty much like the intructions. about a week went by and I still could smell the plants. I kind of let it go for awhile as no one was really going down there, it's just my wife and me. ( my wife doesn't even know about it, it is going to be a surprise)

anyways, my parents were coming to visit for a weekend, and since my mother has an unnatural sense of smell, I thought I should fix it. well, the problem turned out to be that the inline fan was pushing TOO MUCH air, so it wasn't filering efficiently. the day my parents were to show up, I went out and bought more carbon filter material and wrapped it over the original filter. essentially doubling the carbon filter.

about 3 hours of cleaning, and 3 hours before my parents were to show up, my WATER HEATER broke no hot water. I had to call a repairman, who showed up about an hour later. I went down to check the growroom smell.

ALL GONE.

The repairman was 4 feet from my growbox. not a smell. Parents here all weekend. not a smell.

so word to the wise. if you are using an inline duct fan, make sure it doesn't push too much air. It will reduce the effectiveness as it filters the air being pushed through it.

What was the free air cfm of the fan you were using? Curious. I dont have a speed control yet for my fan and wondering if I should grab one.

As far as I know, it should. Everytime I see someone ask where to get activated carbon, people tell them to look in the aquarium section.

Hi all,

first, go to say thanks for the great job!!

just 2 things:

Is the carbon already in the filter, therefore no need to add it in mesh roll?

and

what exactly is the black material rolled around the outside of the c. scrubber?

Many thanks,

and love the website!

Does it matter which material you use to make the tubes out of? For example, could you use plastic pipes with a ton of holes drilled into it?

thanks

I want to get this Panasonic WhisperCeiling bath fan:

http://www.google.com/url?sa=t&source=web&ct=res&cd=8&url=http%3A%2F%2Fpanasonicvu.buildingmedia.com%2Fstudyguides%2FWC_FV-11VQ3_Spec.pdf&ei=qXqoSuuTEI2SsgPh6p37BA&usg=AFQjCNFuLZQjtTZeYubMU8afJHb9i0KO5A&sig2=K6ZT65oIo0BrAmqrEBdq8A

I think it would be enough airflow for me even at 6.5" of static pressure, by the graph in the pdf. Has anyone tried using this with a similar fan and know if this would provide any air flow at all with this filter?
