AIRBORNE PATHOGEN AIR FILTER/PURIFICATION SYSTEMS USING NANOFIBER FILTER MEDIUM FOR COMMERCIAL, INDUSTRIAL, AND AIRBORNE APPLICATIONS. The core of this filter technology was initially developed for NASA for use during crewed space flight applications that lasted for more than 120 days to provide ultra-fine particulate matter air filtration and purification. The performance has been enhanced further with the addition of nanofiber filter element materials. The porous nanofilter media is enveloped with an electronic field that causes the airborne particulate matter to move in a churning motion perpendicular to the airflow direction without ionization, thus significantly enhancing the London/Van der Waals force interaction (a method of intermolecular attraction), and resulting in a super-efficient air filtration and purification system. This system effectively captures bacteria, viruses, smoke, dust, odorants, and other sub-micron sized particulate matter. Unlike traditional filter technology that relies on ever more restrictive filter elements and reduced flow rates in order to catch smaller particles, nanofilter technology provides nearly unrestricted air flow, minimal pressure drop, and a substantial increase in energy efficiency. We have tested this filter using both the SARS virus and anthrax, and found that it effectively filtered both. We believe that immediate applications for this technology exist for installation in industrial, commercial, and residential buildings, as well as in mass transit vehicles. Filters suitable for commercial HVAC applications are currently in prototype production, and we anticipate that they will be available for installation by December 31, 2003. We believe that immediate opportunities to market this product exist in Asia, with the most urgent requirements being hospitals and health facilities that are combating the SARS epidemic. A single hospital HVAC system currently contains 4000 standard filter elements. These elements require changing at least 4 times a year. By installing a nanofilter, a hospital can reduce the energy consumption of the HVAC system by up to 35% and have a more effective filtration system.
