MountainAir carbon is derived from an allocthonous, subbituminous black coal deposited in the Devonian Period in a PreCambrian formation within the Collie Basin over 230 million years ago. It is the planet s oldest coal. It has extremely low ash content. Trace element discrimination
demonstrates it to be physically and chemically unique.

This feedstock is steam activated in the presence of large concentrations of particular gases that affect the activation process in a certain way. The result is an irregularly shaped activated carbon granule predominated by mesopores in a physical distribution which is absolutely ideal for adsorption of volatile organic compounds as well as other associated odorous particles.

MountainAir filters will remove most VOCs of less than 30 microns, including acetone & acetate compounds, alcohol compounds (butyl base, ethyl base, methyl base & propyl base), animal odors, benzene compounds, cooking odors (low humidity), diesel fumes, epoxy resin odors, glue odours, paint odors, all plant odors, pollens, some poisons, odour-bearing smoke particles, and most welding fumes. MountainAir filters are less efficient at removing large smoke particles but are extremely efficient at preventing and/or minimising smoke damage to fabrics et cetera.
