Duct Carbon Filter 4-Inch

The Duct Carbon Filter (4-inch) is designed for hydroponic setups and grow tents, although it could also be a great addition to smoking areas or kitchens. Constructed with an Australian Virgin charcoal bed, evaluated at 1200+ IAV, this filter has proved an updated absorption rate in comparison to other industry-standard filters. The higher microporosity of the charcoal bed permits higher airflow. With a lifespan of up to 33% longer and heavy-duty aluminum flanges with a dual-sided galvanized steel mesh, this duct was built to last a very long time. The rust-resistant gunmetal finish and a machine-washable pre-filter cloth make this filter as durable as it can be. The accessories, including two straps and two rope clips, make it easy to install in any growing setup without any struggles. The Duct Carbon Filter 4-Inch air filter offers a maximum airflow of up to 210 CFM. Need more power? Consider the Duct Carbon Filter XL 4-Inch, which offers an air flow of up to 300 CFM. Need even more power? Consider the Duct Carbon Filter 12-Inch, offering up to 1668 CFM.
