Air Filtration at Molecular Level

Air Filtration at Molecular Level Air filtration, as commonly understood and depicted in air conditioner advertisements and the print media, is about the poor quality of air around us, which mainly pertains to filtration of particulate contaminants. This article, however, will discuss various aspects of air filtration at the molecular level, i.e. filtration and removal of gaseous contaminants. Air filtration at the molecular level is often referred to as gas phase filtration. Today, when technologies and equipment, especially in mission critical facilities, require a clean environment to function at their optimum, an understanding of molecular phase filtration is essential. This article will also discuss the concept, need, technology trends and equipment for molecular phase filtration.
