Carbon filter vs Carbon filter scrubber

I have carbon filter scrubber for a small 2 x 2 x 4 Grow tent what would be the best way to set the filter up Not a lot of room in tent



I have a 2x4x5 and install fan,filter outside the tent.

Stand the filter on the floor, put your fan directly on top and feed your flex ducting into the top of your tent. You can also stick a pre filter in there if need be. Put a Dyson filter or similar over the inlet at the tent end if you like

On top of the tent works great. I wouldn’t put the filter or the fan on or near the floor unless you have no other choice. Heat rises, and it’s not easy on an exhaust fan to push it down. Much better to let it rise like it wants to rather than fight it.
