The core of US GLobal's NanoFilter technology was initially developed for NASA for use during extended 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 using a matrix of submicron nanofibers in the filter element.

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), resulting in a super-efficient air filtration and purification system to effectively capture 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 is designed to provide minimal pressure drop, which results in an increase in energy efficiency. The Nanofilter's core technology has been independently tested and has documented its capability to contain submicron particulates of the same size range normally associated with Anthrax or the Sars virus. We believe the Nanofilters mass appeal lies in its energy efficiency and ability to improve indoor air quality - all of which have a major impact on the workplace.

Nanofilter technology is suitable for industrial, commercial, and residential buildings, as well as in mass transit vehicles. Filters suitable for commercial HVAC applications are now in prototype production.

By installing a Nanofilter, we believe a hospital or commercial facility could reduce the energy consumption of the HVAC system by up to 35%(as indicated by independent analysis)and provide improved air quality. The company is currently pursuing a wide range of applications for Nanofilters both domestically and abroad.
