New Rhino Hobby Carbon Filter Range


Rhino are the world’s leading hydroponics air filter manufacturer. The brand new range of Rhino Hobby carbon filters are made with the same virgin Australian carbon as the premium Rhino Pro range: RC412, but they have a shorter lifespan. Rhino Hobby carbon filters feature a swappable bottom and duct-coupler and they should be turned around every 8-12 weeks to even out the wear ensuring the filters last for their full 9-12 months expected lifespan.

The carbon filters in the Rhino Hobby range do not last as long as those in the Rhino Pro range. Typically, a Rhino Pro carbon filter will last 2 years or more, and the ends never need to be reversed. A Rhino Pro carbon filter typically costs about 40-50% more than the equivalent Rhino Hobby carbon filter, but the Rhino Pro will last 100% longer making it a much more economical choice in the long-run: Rhino Pro Carbon Filter 4″ (100mm) x 12″ (300mm)
