THE CONTROL OF NITROGEN OXIDES FROM MOTOR VEHICLE EXHAUST FOR IMPROVED INDOOR AIR QUALITY
The health effects of automobile and diesel exhaust are well documented. As cities become more crowded, the number of people affected by this type of air pollution will increase as well. Research has shown that an air cleaning system using a single gas-phase (or dry scrubbing) air filtration medium is not adequate for the control of the major gaseous contaminants found in motor vehicle exhaust. A new permanganate-impregnated alumina media provides for improved control of NO2. Application of this and other dry-scrubbing media types into a nonwoven fiber matrix provide higher removal efficiencies and lower pressure drops than traditional air cleaning systems and can also be produced with integral particulate filtration for more complete control of automobile and diesel exhaust emissions. This paper will present information and comparative test data on this new dry-scrubbing medium, how it is incorporated into a nonwoven fiber matrix, and how a combination chemical and particulate filter product is being used in air cleaning systems for the control of automobile and diesel exhaust.
