My $3 Carbon Filter

That is some good information right here!
I like that they are refillable as well.

Just wanted to add my own congrats ... this is exactly the kind of thing that really helps many growers - cheap and effective. Way to go and thank you for sharing.

PANHEAD YOUR FILTER IS THE SHIT...... I MADE ONE AND NOW I HAVE ZERO SMELL IN MY HOUSE, AND IT USED FILL MY ENTIRE HOUSE! $3 AND THE SMELL IS GONE! you should market that shit......

Excuse me but wtf. Can I see one of these installed and running? I don't get it..I'm probably too high but when I was here like 2 weeks ago I still didn't understand it.

a scotch brite wash cloth, and the activated carbon that you buy for a fish tank. sew the wash cloth until you have just enough room to dump in the carbon. then finish sewing it up. how you attach it would be specific to your grow op. i just shoved mine right into the exhaust tube, the air blows through it just before entering the rest of the house.

Thank fucking god someone has a brain and can show you how to use it. I get how to make it but wtf, I just didnt understand howyou were supposed to use 2 bags as a carbon filter. Sticking it in the vent didnt come to mind.

great fucking idea panhead...+rep for that tip, i need one too, my plants are just starting to smell

the other idea i had was making the bag oversized so i could rubberband it to the end of my exhaust tube, so that it's attatched to the end of the tube instead of sitting inside it, but inside works fine so I'm not gunna change it.

Genius... .sheer genius Pan!

Thanks for sharing the idea!!! I am definitely going to make some of these..... and being the crafty woman I am.... I'm going to use my sewing machine.... and I'm also going to sew in a 2 inch piece of Velcro to make refilling even easier.

I'm thinking I can whip up 4 of these in under 10 minutes.



P.S. Your idea should ABSOLUTELY be in the Grow FAQs .... do it yourself..... odor control section

Wow thats quite a statement on the grow faq,thank you,im glad its what your looking for.

On a side note my wife is a hell of a seamstress,im going to add your velcro idea to my next batch of filters but have her make them this time.

The material is a very porus wash cloth thats hemmed up into a bag,after they are filled you have a shit load of options on how to use them,stuffing them in the pipe,securing them on the outside of the intake fan(or pipe) with zip tie's or radiator clamps ,or even tape will work.

Glad to hear it,that kinda feedback makes me feel good as hell,i dont get too many good ideas anymore,getting old sucks balls

Oh, I love it. Rep for you buddy!!

Awesome post. We were just wondering how we were going to control the smell when this girl gets more buds and during our next grow with many more plants. Now we have the answer!

Im glad you liked the design,i can tell you that they work very well & for alot more than just a few plants too.

How long do you think they last? Do you think it would be a good idea to smash up the carbon to begin with to increase surface area?

I wish i had a good answer for you but i dont,ive been using them for nearly 4 months now & their still working like new,as for smashing up the carbon i did just that on a few of the one's i made,the ones with the smashed carbon do not work any better or worse than the unsmashed filters.

I personally think it's better not to smash the carbon right from the start,in the event they start to allow smell to pass months down the road you'll have a 2 minute quick fix at hand by smashing up the carbon.

You'll finish an entire grow before you need to smash the carbon, that i know for sure cause ive just finished a harvest with them & their still working.

so does anyone think this would work? i took toilet paper roles cut a odor attracting filter into about the size of one peice of tp, rolled it up stuffed it in a tube, then using the same material(this material has metal netting in it..) cap it off, then fill it with alternating 1 in layers of the material and then crushed up carbon. i did this four times, stuffed it into the exhaust, filled the space. now they just need ta get stinky enough to mask em haha

well looks like you gonna tell
us if they work or not.

Sounds like a good design

Seems like you can tweak this cloth/carbon idea to fit any ventilation setup really
