Pro-Grow Premium Carbon Filters are made of galvanized steel rather than aluminium, making them easier to transport and less likely to dent (internet sales).
They come in discrete packaging and have clever built-in hanging brackets to aid fitment. ProGrow carbon filters are the result of years of research and development in order to find the most effective carbon grade and filter design.
ProGrow filters have a 50mm bed, which we believe is the best balance of lifespan and airflow. The more dust carbon a filter contains, the harder any fan pulling air through it must work.
The carbon is sourced from Australia because of its consistent quality and unique composition, which provides a greater internal surface area than carbon from any other country.
Don’t be fooled by other brands marketing their carbon as 4/12; it’s not the same if it’s not Australian virgin granular 4/12.
The more internal surface area carbon has, the more odours it can absorb and the longer it will last.
ProGrow filters are made with virgin granular 4/12 graded carbon, which is larger in size than some other brands.
