Whats up DGC, need some advice here. I have a carbon filter for my exhaust already. Just got my air conditioner in, it has a 6 inch exhaust that goes to a baffle outside. (Portable ac unit) But the smell is coming out of it pretty heavy. Im looking at a INLINE carbon filter for it. But its $220. Would a carbon filter hooked to a fan inside the room filter the room enough? Cause that would be much cheaper. On week 6 of flower, and the smell is getting dank. Thanks and happy growing!
