There are no other materials, natural or man-made, that will do all that it will do. For all HVAC applications, where the concentrations are extremely low and the contaminant loading varies constantly, adsorption has proven to be the most effective and the most economical means.Īctivated carbon is truly a unique material. Adsorption with activated carbon is therefore the process of choice for applications when vapors are present in low concentrations. Very simply, particulate filters do not and can not remove material that is this small and is a gas. Benzene and naphthalene, two compounds that are strongly adsorbed by carbon, are approximately. HEPA filters can remove particulates in the 0.3 micron range and below. In order to remove the chemical pollutants from gases and vapors, HEPA filtration is the most effective means. Theoretically, we can remove almost all particulate matter from an air stream.

Many have been in use for decades and have proven to be effective in eliminating the chemical pollution found in HVAC systems. Activated carbon, known as the universal adsorbent, is the most effective means of cleaning the air we breathe.Ī variety of products utilizing activated carbon are readily available. However, to totally “clean” the air the gases and vapors – the chemical pollution that affects heath and productivity – must also be removed.įor HVAC applications, adsorption is the most effective and the most economical process. The air movement industry has been very effective in the areas of human comfort and the removal of particulates. Improved indoor air quality is a major issue facing the HVAC industry today.
