The Pure Factory Carbon Filter 125/600 (450 m³/h) is an activated‑carbon canister for indoor grow odor control. It uses 4 mm CTC70 carbon in a metal housing and is intended for the extraction side of your ventilation system, so air is pulled through the carbon and exhausted outside. This variant has a 12.5 cm (125 mm) inlet and a 60 cm body length, with a maximum rated airflow of 450 m³/h. Select capacity to match your extractor to maintain adequate contact time and effective odor removal. The filter is compatible with standard 125 mm ducting and inline fans.
