Carbon Air Filter

Ive been lookin on ebay for Carbon Air Filters and it seems that they have the cheapest ones on the internet! has anyone ordered one from ebay or know if they are good filters? or anywhere else i can get one for cheap? they are running on ebay for $70 to $120 and thats the filter, fan, and carbon!

Hey I went to Wal-Mart last night and was looking to get an air purifier. I came across a Febreeze activated carbon fan thing for $14. It plugs into a wall outlet. I put it right next to my exhaust of my grow box. I don't have much issues for smell right now, so it is hard to tell if it works good. 1 1/2 week of 12/12 so far... The activated carbon is supposed to last a month or so.

They also have a big sheet of activated carbon for bigger air purifiers for like $10. You can cut up a piece the size of the old one and replace with that.

Depending on how big of a grow op you got, you might want to look into that.

I do know that ebay does have a lot of growing stuff very cheap. I got a 400w hps for $20 one time.

I would recommend making a couple of these. They are effective, cheap and it is easy to replace the carbon down the road. Took me about 15 mins once I got home from the Depot.

yes i have also lookd at all sorts of different homemade carbon filters and have heard good feedback and its reaaal cheap..but i have also read that they do not work as well as one bought off ebay or an actual gardening store? is this true or no? i just have had trouble finding the right fan for a homemade filter becuz i need one with a switch to control the fan speed, as quiet as possible and inexpensive...any suggestions

YES in fact i ordered one last monday and had it by wednesday £100 w/d and it has already made a difference to the heat and smell in my closet and the room in which the closets in

to find out what size of fan and filter you need for your grow space

take the width and times it by depth then times that by the hight

so (w)x(d)=? x(h)= ?M3 and that the size of fan/filter you need i went about 2xs bigger then what i needed

sure if im wrong with that ^^^ some one will say

yea i have done that but i jus cant find a fan that fits my specifitcations..inexpensive as possible, switch to control fan and quiet as possible

well one thing for sure the RVK fan that came in the kit is supper quite its no more louder then a normal fan

if you cant afford a kit try looking for just the fan then building the filter like has already been said

but the question is how good do they work? good enough to cut corners on this and save the money for something else or to save for a good lawyer

yea i can more then likely afford a kit, so u payed like close to 200 USD for your filter?...do u have a picture or anything of the filter u bought?...there is two i am lookin at on ebay but only one of them has a switch to control fan speed

thats it but it doesnt have a fan speed control but guess you can pick one up from a shop in town or one on ebay

yea for some reason i cant get the picture from ebay..but if u type in carbon air filter under home and garden there is two black air filters all put together..let me kno wut u think bout em

My grow room (at the time) was 10' x 10' x 8'. And I used the biggest badest carbon can that I could find (it's fricken big) It worked so well that when I reduced the size of my grow room down to about the size of a double door clothes closet I stuck it in there and WOW I never had heat or smell issues.

So any way I needed to expand my grow a bit (flower room, veg room, and clone room). I kept the big carbon can in the flower room and went with the home made jobbie for my veg. room. It works so well, and all I have to do is go to the fish store to buy my activated carbon ($7.95) Not only cheap to build, but cost very little for the carbon. As for fans, heres is what I did......

Since I was using this as an exhaust I decided to buy an inline duct fan ($14.95). Works really well and my veg room had very little oder, which I cured that with a Pine Christmas Tree car air freshener! Now all I smell is pine!

is the inline duct fan quiet?

Extremely quiet kinda like a bathroom exhaust fan, but just a bit quieter.

lol well my bathroom exvaust fan is loud...like is it quiet to where u have to put yer ear kinda close to it to hear it or can u hear it in the same room pretty good?

Wow, I never had a loud bathroom fan! I guess it would be more like a cumputer fan quiet! Hardly noticeable. A light whisper sound. And most of them out there are ball bearing type of fans, which is a good thing to help prevent a fire!

thanks for the help! would u wanna chekc out the carbon filter i was lookn at on ebay and let me kno wut u think bout that compared to building one myself...jus type CARBON AIR FILTER under the home and garden category and there is two black ones with the fan built on..one has a switch to control fan speed..let me kno wut u think!

They both look like real nice units. Nice to have speed control. I would buy for a small grow op. The price is right as well! Maybe the better way to go if you can tolerate the sound of the fan blowing.

whys that? do u think these units will be noisy?
