Product Description

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 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. Includes two machine washable pre-filter cloths to prevent carbon residue and two hanging straps for easy installation.

Premium Grade Carbon

Each carbon filter features premium-grade Australian Virgin charcoal bed rated at 1200+ IAV. It achieves a 38mm charcoal bed thickness and wider mesh openings thanks to a higher microporosity and surface area rating. This combination not only enables a higher adsorption rate without restricting free airflow, it allows the carbon filter to last up to 33% longer.
