Our Carbon filters use Australian Mined Carbon. This is the end result of processed coal. This process treats the mined material with oxygen to open up millions of microscopic pores between the carbon atoms. The result is a uniform carbon with a surface area of up to 2,000 square meters per gram! This amazingly porous substance (which is not only lighter than plant-based carbon, but 2 to 3 times as porous), is now ready to absorb over 100% of its own weight in odor producing particles.
Our Carbon Filter Kits include a filter, inline fan, and 25 feet of flexible aluminum ducting.
