4" Rhino Hobby Filter
Rhino Hobby filters are filled with the same high quality Australian mined RC142 carbon as the Rhino Pro range of filters, which is the finest quality carbon available for air filtration. A 30mm carbon bed is tightly packed into the airflow cylinder making it highly effective at attracting and absolving the air of pollutants. The smaller bed depth of carbon to that of the Pro filter makes it an even easier to handle and manage for the novice grower. Additionally, with its fully reversible neck, the first of its kind on the market for a hobby filter, the Rhino Hobby benefits from a fantastic 9-12 month lifespan, Unlike other budget filters the reversible neck pro longs the life of the carbon.
