A high-airflow duct filter designed to eliminate odors and chemicals, utilizing a premium-grade Australian Virgin charcoal bed. This activated carbon bed has RC412 pore sizes that enable a high adsorption rate and longer life rating. Its heavy-duty construction features aluminum flanges and dual-sided galvanized steel mesh with a rust-resistant gunmetal finish to stand up to corrosion and high humidity. The carbon filter can be used with an inline duct fan for use in intake and exhaust configurations, while its flanges can be reversed to further prolong its lifespan. 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 carbon rated at 1200+ IAV. It comprises a 38 mm charcoal bed thickness that has a higher microporosity and helps achieve a greater surface area rating. This, when combined with its wide mesh opening, not only enables a greater adsorption rate without restricting free airflow but also extends its lifespan by up to 33%. Most used in hydroponics systems, grow tents, grow rooms, kitchens, smoking areas, and other ventilation projects.
