Airontek’s Filter 150-650 is an activated carbon odor filter built for 150 mm ventilation lines in indoor grow rooms. It pairs a 150 mm flange with a 650 mm canister and is intended to be coupled to an extractor so air is pulled through the carbon bed before exhaust, adsorbing odor-causing VOCs. Airontek lists this size at 980 m³/h airflow, calculated per hour of operation. Retail listings confirm the 150 × 650 mm format for 150 mm ducting and typical use on extraction circuits. For best results, select an extractor with nominal flow 20–30% below the filter’s capacity to maintain contact time and avoid overloading the fan. The length and larger capacity suit medium 150 mm systems needing stronger odor control.
