KFI 4′ Flange for Plastic Filter is a Kootenay Filter Inc (KFI) carbon filter built for serious odour control in grow tents and rooms. It is filled with high-quality activated carbon that traps smells as air is pulled through by an inline fan. Match it with an appropriately sized inline fan for balanced airflow and filtration. Use it on your exhaust line or as a recirculating scrubber to keep your space smelling clean and discreet.
