RHINO HOBBY FILTERS 150mm Specifically designed for hobby growers – made with the same pure Australian carbon as premium Rhino Pro filters. With a smaller carbon bed depth than the Pro range, Rhino Hobby filters are easier to handle and perfect for the novice or occasional grower. These reversible filters feature a swappable base and duct-coupler. They should be turned around every 8-12 weeks to even out the wear of the carbon. This will ensure the filter lasts for its full 9-12 expected lifespan. A 30mm carbon bed is tightly packed into the airflow cylinder which makes the filter highly effective at removing pollutants.
