Do most pull air through a carbon filter and have it exit through an exhaust fan or push it through the carbon filter and have it exit the filter on its way out?
I think he means do you put the carbon filter before or after the exhaust fan. My carbon filter is going behind my fan, the exhaust fan will push air into the carbon filter. Not sure if this is the best way, but its the best for the amount of space I'm working with.purpose of the carbon filter is to suck in air from your grow room and exit through the filter.. any air carrying odor gets trapped in the filter. just think of it this way... the air that comes out of the grow room do you want it to smell? if not.. make that air coming out go through a filter.. kind of like when you put some pasta in a pot that has those holes.. you want to eat the pasta not the water and pasta
It will work but the filters are designed to suck air through the pre filter for larger debris and then the carbon for odor. If you push air through it, you loose the use of the pre filter and the carbon won't last as long.I think he means do you put the carbon filter before or after the exhaust fan.

Old post but ppl still read em, so ill go over what I do and why.Do most pull air through a carbon filter and have it exit through an exhaust fan or push it through the carbon filter and have it exit the filter on its way out?
Sorry to bring up an old thread but i am really trying to figure this out before i start my grow;Old post but ppl still read em, so ill go over what I do and why.

If you do this

Larger particles that can get stuck in pre-filter "cotton, cloth etc" will do just that
You can litterally double the life of the carbon inside your filter.
however ive found with pushing consider your fan to have 0-10% less CFM
dependong on how cheap that fan is.
And rarely in our tests "University class" was it 0%. usually around 8%
So you need a bit more "fan" to pull that air and increase the life of your filter
if you do this
>>>> ========X===== >>>>
Air flow from your fan is not lost, larger particles get stuck in carbon and
it makes pre-filter useless,
you can "DIY" a scrubber and put the pre-filter first, but its not easy! and
never seen any manuals online doing it that way, but its possible.
Gaps can leak air before the filter and odor will escape, even if this occurs in the
other setup the air is cleaned already, no big deal.
The filter in this setup will have to be outside of your grow space reducing its
"stealth", if all your worried about is odor to your neighbour no big deal, but if its a cabinet in plain site you may wanna go the other route.
so in our conclusion:
No method is superior, they both work equally. however
each has its own flaw, you will need to choose one.
Filter life and more CFM required
Loss of stealth and possible leaks.
We did this test 4 times.
I haven't been on here in a while, just been doing random grows tryna get the funds up for the dream grow Finally getting there so I figured I'd come back and post about it, should be running in a couple months Good to see some of the same people still hanging aroundWhat up Bwpz havnt seen you in a min since you did that spice devil and king kush grow! .............Ive always set up my carbon filter on the floor with inline connected pulling the air into ducts and out the room. Preferably you want to mount it High on the ceiling , but my carbon filter is damn heavy and to lazy to bother finding studs and anchoring it to ceiling so i just put it in the corner of the room! Pull Thru the filter
