The easiest is to just use an inline 6 inch fan, drill a 6 inch hole in your cabinet and attach the fan to the cabinet then attach the scrubber to the fan.
killerweed420 Reviewed by killerweed420 on . Confused about carbon scrubber I have done alot of research on here about exhaust and carbon scrubbers. I read the DIY section about carbon scrubbers but I don't understand if that device is inserted in the ductwork or simply sitting outside the cabinet. And if it is inside the ductwork infront of the exhaust fan, how is this attached for maximum efficiency? Thanks alot! Rating: 5
