Rhino Hobby 30 Filter — 150 x 600 mm is an exhaust carbon filter for 150 mm ducting, 600 mm long, rated up to 900 m³/h. It uses a 30 mm bed of virgin Australian RC4-12 activated carbon in a lightweight aluminium canister with perforated mesh for even airflow. The reversible neck and swappable base let users rotate the filter to extend its typical 9–12 month service life. A machine-washable pre-filter sleeve is included to catch dust and maintain performance. Intended for scrubbing odours and VOCs from extracted air, it’s commonly paired with a 150 mm inline fan in small to medium grow rooms or tents. Dimensions and rating correspond to the 150 × 600 mm Rhino Hobby 30 variant.
