Indoor air in work places, automobiles, recreation settings and homes is one of the major sources of direct human exposure to particulates, chemicals and disease causing bacteria. Recent estimates suggest that more than 98% of these particulate pollutants are very small (less than 1) and, therefore, cannot be effectively filtered by exiting filters. These particulates are also know to be carriers of chemicals such as volatile organic compounds (VOC) and bacteria. Therefore, it is very important that a low cost, low pressure drop, high efficiency filter that can effectively remove these particulate pollutants be developed. Nanomaterials Research Corporation will during this program develop nanoporous filters from proprietary precursors that have the ability to filter sub-micron particulates efficiently and also completely mineralize any VOC in the feed air stream. Phase I will establish the proof-of-concept that nanoporous filters can be produced and the filters can simultaneously remove VOC and particulates from air. Phase II will systematically develop and optimize nanoporous filters, and Phase II will commercialize the technology.
