The high-airflow duct filter is designed to use activated carbon to eliminate odors and chemicals, popularly used for hydroponics, grow rooms, kitchens, smoking areas, and other ventilation projects. Features premium-grade Australian Virgin charcoal bed. The filter can be used in conjunction with an inline duct fan to act as both an intake and exhaust configuration. Heavy-duty construction contains aluminum flanges and dual-sided galvanized steel mesh. The flanges can also be reversed to prolong the life of the filter.
