Rhino Hobby 30 Filter 100 x 300 mm

The Rhino Hobby 30 Filter in the 100 x 300 mm size is a cylindrical carbon filter designed for small grow spaces and extraction systems. It uses a 30 mm bed of virgin Australian RC4-12 activated carbon to adsorb odours and VOCs. On the official specification, this 100 mm diameter, 300 mm long model is rated for a maximum airflow of 350 m³/h. The Hobby 30 features a reversible neck, swappable base and duct-coupler so the filter can be flipped mid‑life to promote even carbon use, with an expected service life of about 9–12 months. It is intended to be paired with a 100 mm inline extractor fan, mounted on the fan’s intake side to scrub air before it is exhausted from the room.
