HEY PAN.. I was searching this thread but couldnt find where the best place to attach the filter? I just dialed my sealed room in with a 6'' inline fan, the negative pressure is great. My fan is 435cfm. Where is the best place to attach this? I vent straight up into the attic, my duct is very short, only like 1 1/2 ft straight up into the attic....i was thinking i could ziptie a filter right on the end of the ducting, so the exhaust air will be pushing through the filter at the end? what do you think? Im gonna have 30-40 small plants in an 8x8x8 room..will this filter do the job?

You want to attach the filter to the intake side of the duct if at all possible,i used large hose clamps from the auto parts store,when i was still using filters for odor control i had no issues with smell in grows larger than what you describe.

The intake side is the fan. Like i said i have a fan mounted on the ceiling, and 1 1/2 ft of duct going straight off the fan up into the attic.
so i should attach the carbon filter bag to the fan? so its sucking air through the filter?

Sorry ,i missed the ceiling mounted fan part,in that case i'd mount the filter on the exhaust side of the duct,hell,try it both ways & see which way moves more air,the main point is that the dirty air is going through the filter.

I dont think there's really a wrong way to use these filters.

Thanks pan... seeing as i already mounted the fan and all, maybe i will just use a hose clamp with two cloths, fill in some carbon and try to clamp it really tight to the fan.

thanks

Do you think 4 80mm Fans Like all together, like mount them in a square shape then make a exhaust box and put these filters on it, do you think that would work? cause thats what i was thinking of doing, my box isnt gonna be that big Its Gonna be 4 feet tall, 2 feet wide, and 18 inches long, with 4 plants growing inside, then i'm gonna have 2 60 mm fans as the air movers on the inside,

Huh ? i have no idea what your asking,i cant picture it in my mind.

If you can mount these filters directly to a standard vent/exhaust pipe they work fantastic,im not sure about highly unordionary applications though,for the cost of $3 & an hours time making them i'd say it's worth a shot.

bar b q char coal works great 2.just make a wooden box 10*10 say 3 feet long seal well with silicone and put in line. so ya room gets sucked up through it and then outside,dont pack it to tight though... like the carbon filter respect to the price it costs about the same as my example.laterz all

Ok tell me if you think this will work? I couldnt find the cleaning cloth you recomended so i bought some panty hose..lol

I have a hose clamp, activated carbon and the panty hose. I was gonna take a leg of the panty and fill with the carbon and attach it with the hose clamp to the intake of the fan. Between the panty and the fan is an airconditioning filter that i already have attached.

Should work fine as long as they are industrial strength panty hose for fat girls :lol:

Hey Panhead - Got a newbie Q for you. There is nowhere to vent exhaust except into the rest of the basement. I have a small basement grow (4 plants) that is in a small room in close proximity to my furnace, which takes 2 large furnace filters (18 X 25). I was wondering if those Filtrete filters would filter out some/most of the odor escaping from the room? (they are good for sig smoke, etc)
I just had to ask. Thanks in advance.

Nope,they wont work for heavy bud smell,let me ask you this,if your in close proximity to the furnace why not vent out the chimney ? you can use dryer vent to get the exhaust from the grow area to the chimney if needed.
