I'd love to see a pic posted (promptly) of this supposed filter in action,how it was installed,what exhaust fan it was connected to ect.

Also, where are you getting your numbers from,you quote "75%" as if your measuring the actual cfm output of your exhaust ,if you are measuring exhaust cfm please let me in on the method you are using to accomplish that task,that shouldnt be too hard an accomidation should it

Nice try bongjuice but im giving you a massive thumbs down for being a petty ass man who holds a petty ass grudge, then letting it carry over into a thread designed to help people with little cash to spend on a filteration system.

Not only a big thumb down on you personally as a man for your childish & petty posting of falsehoods but a negative feedback to boot, for letting your pettiness carry over out of toke n talk.

Come back with verifiable measurements of what you spew or beat it

Your Unfucken believable.....
Even though I don't have any odor issues, I take the initiative to try your so-called cheap method for a filtration system.
I tried it and gave my opinion in mature way, by saying I give it a thumbs down.
In return for my initiative, you not only give me negative feedback but you call me names also.
I'm not being childish, I'm not being petty.
There's no grudge, I saw your idea and thought....WOW, I wonder if it works.
If your idea worked I would of given you a positive feeback.
What the fuck is wrong with you?

If you wouldn't of lashed back at me like I was making personal attack against you, which I wasn't. I would probably show pics of the filtration system I made with your cheap method. But since your so highly sensitive and enjoy giving negative feedback to me, you'll just have to wonder how I did it.
You truly are an asshole who needs serious fucking mental help.

Your welcome,the filters actually do work very well.

Great Idea! I was curious what this would do to CFM's as well. Is the reduction similar to a Can Fan Filter (about 150 or so is the rated reduction I read somewhere?)

I have a room that i was going to use a 6" Hight output fan to pull through a Can Filter 75, or maybe a 66......wonder if the fan and this set up will match or if the fan will be too strong now.

Interesting feedback from BongJuice and somebody else who reported severe reduction issues.

Anybody else have any feedback on a "room" sized grow?

i have no doubt the concept is a solid one.
i am going to build my own filter soon but.

where can i get Carbon in larger quantities?
i have an idea for a filter i hope it works. ill be posting pictures once i have it up and have tested it myself.

Thats a good question,ive heard other mrmbers talking about large quantities of carbon being found on ebay but i dont personally know,i just buy mine from walmart or a fish tank store.

What kind of quantities are you guys talking about?
How about this...?

Here is a way to make carbon filters for less than $3 each,they take about 30 minutes to make & all components & materials can be bought at any meijers store.

Materials needed.

1 4 pack Scotch Brite cloth towels from Meijers............$2

1 Bottle Activated Carbon from Meijers or fish store......$6

1 sewing needle & thread from Meijers........................$2

Total cost for 4 carbon filters...................................$10.

First you start out with the Scotch Brite cloth,its very thin & extremely strong,i find it much stronger than aluminum window screen material,its next to mpossible to tear yet the weave of the material is such that it will not restrict air flow.

Take the Scotch Brite & fold it in half or to a smaller size to fit your needs,like this.

Then take & sew 3 & 1/2 sides of the Scotch Brite closed making a pillow case looking thing,make sure to leave a few inches open to fill the "pillow case",then pour in the Activated Carbod to a little less than half way full & sew up the spot that was left open to pour the carbon in.

Here is the carbon.

Here are 2 finished Carbon Filters.

As for attaching them to what you need to there are several options,there is always duct tape in a pinch but i connect mine using hose clamps from the hardware store,the hose clamps make it easy to take the filter off if needed & is more secure that tape.

These work every bit as good as a $80 carbon filter i bought off of ebay & cost less than $3 each & about 2 hours time to make 4 of them,its not getting any cheaper than that.

You place them over & secure them to the powered exhaust from your room.

pan sell these and pattent before someone else does

As long as the filter one layer it will be fine.

The only way your grow op wont stink inside the room is to run ozone generators or serious in room filtration,the trick is to keep the stink within the room

Not necessarily true pan.......

(although I did rep you for this because you solved a problem I had designing my anti-stinky dogs filter in the middle of the house but still looking good filter)

I built several of the tube style carbon filters with built in fan to do this very job. The work but are actually pretty unsightly. By your quote they wouldnt work because they arent bringing in fresh air and expelling the now reduced smell.

If you have a good activated charcoal filter in place in your grow room it will filter all the smells out, granted it must be sized large enough to filter the cubic feet amount of the room at a fairly rapid rate to not allow the smell to permeate anywhere.

What a lot of folks confuse is that the majority of ya use your filtered air as a temperature reduction outlet as well. While this is all well and good, its not actually necessary in the sense that it is required to eliminate the odor.

I was so fascinated by everyone's ingeniousness about odor reduction Ive applied it to several aspects of my life from the stinky dogs to obnoxious smells I produce tinkering with automotive applications.

I just wanted to build a better mouse trap so to speak and be able to have some in the house without having the unsightly "abominations" most of these things are. I also didnt want to spend several hundred dollars doing it either cause you can buy fancy stuff like that already.

Ozone generators are nifty gadgets but not something I would promote at a heavy level to average people as it can be dangerous.

I would openly suggest that someone who was more concerned with getting rid of tell tale odors over the venting of heat just get themselves an oversized fan, perhaps a large tube style filter (yes I know they are not cheap people.........but I am planning on making something really cool and it may help alot of people out) and filter the room like crazy. It will only pull impurities out aka smell...........and then set your heat vent fan up to a thermostat and it should only come on when the temps tell it too.... no smell problems, no having to overcome the drag induced from the filter (smaller *quieter* vent fan) and happiness.

I hope you dont take this as me stepping on your toes. Im just trying to clarify some minor points and make some necessary changes.

Oh and for the few of you who are smashing those bags into things........the air leaks you have in the folds are just that.......LEAKS and smells will come out of there. Air will take the path of least resistance and that is thru your leaks, not getting filtered.

hey how much of the liquid carbon do you put in one of those sacks?

sorry for the stupid question...does using carbon filter replacements work as well?
Please let me know. Thanks

alright , i've read every page of this thread and seriously , this forum fucking sucks balls i was seriously considering starting my grow journal here to get to know some of the non-shitheads around here , but holy fuck the degree of faggotry/bitching/moaning that i've come across in many sections and various threads disgusts me , go fuck yourselves i'm out. consider this my last post , i'm going back to grasscity where people don't act like 14 year olds fighting over some stupid show on tv

And here I was thinkin of getting chicken wire, clamps, all different mesh, etc..

thank you, pan

hi panhead

i've read this thread with great interest (not the flaming parts tho). you've been most helpful in sharing your solution. i too, like a previous poster, have a grow box in a cupboard, currently under construction, where the door will shut most of the time and no real possibility of venting to atmosphere but i'm sure your idea would be my best bet.

my thought on the bags for lazy people, instead of sewing them or sew in a velcro opening would be to use sticky back velcro on all four edges.

my thought on using your custom bag solution for my predicament, is to attach one to the front of my high cfm fan which is used for air recirculation/cooling in the cupboard. i would love to hear you thoughts?

cheers
