The filtration media of the ESG Chem-X filter consists of a layer of activated carbon sandwiched between layers of inert plastic mesh.  The media is pleated to achieve a large cross-sectional flow area in a limited filter volume. Both the media and the pleat configuration and construction are ESG proprietary designs. The filter size is 2’x 2’x 1’ (appx. 61x61x30.5cm) and fits easily into existing air handling systems. Several ESG Chem-X filter lots have been manufactured, met rigorous U.S. government testing guidelines, and have been installed into U.S. government buildings and facilities. The expected filter lifetime, under 24-7 continuous operation, is greater than one year, thus keeping the life cycle cost low.
