Easy to Build DIY Carbon Filter

fuckin rites i made a carbon filter wheres the best place to purchase the carbon.

you can get activated carbon from most aqurium store, I built mine using a big tin, activated carbon, tights of my gf and black tape

I see DIY threads for carbon filters all over the web. Clearly these designs work, otherwise these threads would not persist.

I'm just wondering about the cost of the carbon. The cheapest I've found is 5 bucks a pound. My turtles' carbon costs about $14.00 per 14 oz; or $16.00 per pound. HTG has a carbon filter (grow bright), 6" intake with prefilter, with (I think) 14 pounds of carbon.

I'm wondering how in the hell you can DIY something comparable and still make it cheaper - much cheaper - otherwise DIY is fool's gold.

Wow...Jesus...it's just so convenient! what area span would this filter be able to handle at maximum?

I followed the general guidelines from this original post to make my own. It's a little bigger since I have a 250cfm fan, and I used 5" hose clamps instead of duct tape to hold the filter on, so it'll be easier to change.

??? like thosse filters look fairly small, as Im hoping to grow 15 plants?....

Great post.

+rep.

I just made mine and it works great. I made mine a little diffrent..with an insert in the inside for more carbon if i ever need it. Its 6" X 20" and reduced to a 4" inline vortex fan. All for $25!!! and the smell is gone. Great idea!! Thank You

Hey Barncle,
What did you use for the insert? I wanna do the same thing.

Thanks!

Here it is folks... hard at work... i will break it down and show you the assembly of the whole thing.. just give me a few days.

This is my whole set up.. it all HO T5 with about 3000 lums per sqrft..


I can make a box like this for just under $500 with 2 150w hps.. i think that is a good deal considering that it is a 2 stage system and you can grow up to 10 plants and 30 clones at a time.

You can have something coming out of the grow box every month..lol

hey guys woundering if i have 2 dif rooms 1 moms 1 flower, flowering room is 6' x 10' x 8' plants in bud room vary depending which moms get to die. from juicy fruit to green crack (very smelly kush bud). 5 wks in and neighbour can smell it . think one of these filters might help? how big should i make filter? any help is muchly apreciated. also does it have to hook uuuuup on your exhaust, i seen them jus in rooms not hooked up to exhaust cause sealed rooms? again thanks for any advice.

There is not a doubt in my mine that this filter with the correct fan can solve your issues.. It did mine...like over night..lol...and it was crazy cheap.. i had fillters for like $300 bucks and this one works just as well is not better.

Cool looking forward to it!

Nice set-up...

GREAT job. I just used this, It's all hooked up to my grow-room. Just getting all my last things in there, I'm looking to get a GREAT harvest. ( This is my first grow... ) Wish me luck, And can you make more of these good ideas? !

I'm dittoing here. Gathering the components for my 1st grow after smoking 40 years. Just got my mmj hook up too.

Big fun.thx

Wondering if using charcoal briquets, for bar-b-cue, would be effective if crunched into small pebbles? Of course without the added lighter fuel.

I would love more feedback from people that have made this. How effective is it? What kind of room can this kind of scrubber keep up with? Any feedback is appreciated.

I made one myself.. havent used it yet, still waiting for my ballast. but it saved me a shit load.

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????

any idea on how long this lasts to cover odors?
