so do you have to let the fan run the through the carbon filter 24/7?

During the end of flowering I do. Before then I don't have it in place usually. Sometimes I turn off the fans when the lights are off, really depends and it's more necessary to keep them on the later you get into flower.

i just dont see how carbon filters work

Carbon eliminates odor
Pulling your stinky exhaust air through it will eliminate the smell
What is there not to get?

not sure if this is easy enough for u but here goes.

the carbon has "pores" in it...... and Activated carbon has even more pores.
these pores actually "fill up" with smell
molecules, and once all the pores are filled the carbon no longer works. Same in a fish tank , the activated carbon takes out impurities like ammonia and others.
Now to me this is BY FAR the best way to get rid of "room odors" , it is very easy to use and really works for "heavy odors"
i got a 40lb carbon filter and im on my 2nd crop with it. some say they last a year some say more or less, all i know is it has lasted over 3 months (24/7)
now if u was to try and take the smell out of a thousand plants then it would probably only last a half hour....... so u decide when its "full"

I had a carbon filter before and it was waay overkill for my size room and 4 plants (according to the manufacturer) but it didnt do shit. Still stunk like hell outside my house

i would love to know how u had it hooked up?
only 4 and it didnt work..... geez what make/model of carbon filter did u use, so i dont ever buy that one
maybe u just had a carbon "sock" ?
(i am using a cheap stanley blower(about 250cfm) to suck mine out and it works great.

Carbon filters only work if your grow room is sealed up. People love to just put a carbon filter in a room with a fan on it (not part of the actual ventilation for the room) and then claim it didn't work.

Or they'll grow in a closet with the door open and complain, well the odor is leaking out the other way! You have to ensure that all of the air leaving the room is going through the filter or they don't work. If you set it up properly, it works AMAZING at removing the odor. I've growin in a 2 bedroom apartment and had 6 plants in my closet. My roommate NEVER knew through 2 grows. Can -66 filter did it's job.

Now I grow in a 4x4 tent in my apartment (no roommate), but when family/friends come over they have no idea. It's completely cleaned, no odor at all. Like I said though, I have coupled it with an ozone generator for when my veg room is running and it's not going through the filter. It dumps air into the same room as the flower tent and the ozone generator keeps everything 100% clean. It's only on 15 minutes and then off for an hour and a half.

Smell? Smell's like the cleanest smelling room in the house.
