2 minute cheap & easy carbon filter (no duct tape)

So after going out shopping, I've had problems finding an air filter. It seems most of them don't have the added plastic piece used to clamp the ducting to it. For example, all the Fram air filters I saw in stores that had the cone shape were completely flat on the other end (no place to clamp on the ducting). I've found some, but they're high performance air intakes and cost 50$+...

Can you recommend an air filter for me. Im using a 6 inch inline duct fan, so ill need one that can clap to a 6 inch or maybe 4 if i get a reducer.

Can always do what I did. I just put a 6in to 4in converter onto end of fan, then put filter up to the end of the 4in, and taped it on there nice and tight. Ghetto but got the job done.

Could this bad boy be used and adapted for a carbon filter eg. Wrap the thing in thing cloth/tight material. Load up the chambers inside with the carbon and then slam a PC fan blowing through it to the outside of a grow space?

air filter 22 bucks from advanced auto parts
active carbon 12 bucks from petco

thats how much it cost me. Seems to work well so far, but I'm only 8 days into flowering. I only used about half the carbon I bought too.

I wanted to use a home depot 250cfm inline fan ($25) but read it would burn out fast due to that it wasnt strong enough to suck through the carbon.which fan did you use?

I am using a similar fan now and haven't noticed any problems. Plus at 25$ a pop, I'm willing to experiment. I also have the filter on the exhaust side of the fan, rather than the intake.

holy shit thats sweet

Nice Thread and demonstration,its exacly what i was looking for

GTEAT idea im running out now to make it WOW good idea! Oh wait everything is closed

Hmmmm......I can't seem to find any stores local to me that sell activated carbon in bags like that...

However, they do sell carbon pads, used for filtering.

If I was to put these 4 carbon pads into a car air filter, you think it'd do the same as the activated carbon pieces?

Super simple, thanks.

how many plants can u control with that? this is just what i was lookin 4

Hey man, when you said
"I am using a similar fan now and haven't noticed any problems. Plus at 25$ a pop, I'm willing to experiment. I also have the filter on the exhaust side of the fan, rather than the intake."
Do you not run a filter on the intake at all? do you get odor escape through the intake? And are you running your fans 24/7?

That is a really sweet idea and will be trying it on my stealth grow cab with a 150w hps and 4 plants. Will let ya know how it goes.

Soz for the lack of replies but been off the forum for a couple of years. Can't believe this thread is still active.

To answer most people. I grew 4 plants and ran the fans almost 24/7 but switched them off for 30 min a day to give it a break.

I ran the fan with no intake filter.

go to any pet store that sells fish tank filter cartridges!..there loaded with carbon!

You will need a quality extractor fan though
