Carbon Filter Size

Trying to find a Carbon Filter/Scrubber that will be inside of my Grow Tent, and connect via ducting to my 4" inline fan. My tent is 2x3x6. Anyone know of any Carbon Filters that wont take up a huge amount of space?

Possibly shorter than 12" in length? Any help is appreciated.

Thanks.

Maybe this?

What is your inline fan rated at for CFM?

190 cfm. Yah that ones 12" too. May just have to go with something like that.

Found an 8" one. Gonna look into it too. Thanks for the help.

No problem, these also work well outside the tent for added measure.

There are calculatrs out there but I always just estimate and add capacity to be safe. Basically if u are using your fan with your filter u want to recycle the room air at least once every 5 minutes. If u are good at algebra plug in your cubic feet room dimensions and calculate Joe many CFMs u need. My method is get a fan strong enough, and a filter a little bigger. For the price they last longer a d u get a better vaue

35 bucks really..yeh ive been looking for a new filter too. i got a room about 2 1/2 ft x 4 ft x 6 ft. i just picked up a 4" fan i think its like 173 cfm. all i need is a speed control and a filter. i had a 9000 for two years now with a booster fan. so would that 4" x 8" work?
