The Pure Factory Carbon Filter 100/250 (160 m³/h) is a compact activated‑carbon canister for odor control in small indoor grows. It uses 4 mm CTC70 carbon and a metal body with 100 mm flange, measuring 250 mm in length. Rated at 160 m³/h, it is intended to be coupled to an extractor fan so smells are removed before air is vented outside the tent or room. The model belongs to The Pure Factory filter range and should be selected to match the fan’s airflow. Dimensions and capacity correspond to the 100/250 variant widely listed by official and brand‑named retailers. Suitable for discreet, low‑throughput extraction lines where a 10 cm duct and moderate flow are required.
