Grow box

Hey guys i plan on working on a new grow box around 4 feet tall and 3 feet wide with a depth of around 3-3.5 feet. The issue i have is that i cant have a carbon filter because it makes too much noise unless any of you have any experience with the noise from a 4 inch filter with fan. I plan on using large case fans to keep it quiet and link it in a cube with carbon filter sheets to take out the smell. Does anyone know or suggest anything for this box its my first grow so thanks all

use a booster fan with a home made carbon filter, its quiet and effective

try a panasonic whisper ceiling fan....What's your temps in the room ? Have to be careful not to get a cfm too low, or it won't cool properly.

I can't even hear the 80 cfm standing almost right next to it. But that doesn't cool my cab as much as I want it to, and I need to add carbon still.
