Improved IAQ continues to be one of the major issues facing the HVAC industry. The air movement industry has been very effective in the areas of human comfort and the removal of particulates. However, to totally clean the air, the gases and vapors — the chemical pollution that affects health and productivity — must also be removed. For HVAC applications, adsorption is the most effective and economical process. Activated carbon, known as the universal adsorbent, is the most effective adsorbent.
