Nano particles of aluminum and barium measure less than 0.1 micron. HEPA, though not certified to filter down this small size, does in fact partly remove these nano particles in independent lab tests I've reviewed. Apparently, the fibers cling to the particles vis weak electrostatic and van der Waals forces, rather than through inertial impaction (i.e. pore size obstruction).Quote:

The idea of spraying aluminum oxide from jet aircraft was patented by Hughes Aircraft in 1990 (see www.uspto.gov, patent #5003186). The plan proposed "to seed the metallic particles was to add the tiny particles to the fuel of jet airliners, so that the particles would be emitted from the jet engine exhaust while the airliner was at its cruising altitude."
SUMMARY OF THE INVENTION: Patent #5003186 A method is disclosed for reducing atmospheric warming due to the greenhouse effect resulting from a greenhouse gases layer. The method comprises the step of seeding the greenhouse gas layer with a quantity of tiny particles of materials characterized by wavelength-dependent emissivity or reflectivity, in that said materials have high emissivities in the visible and far infrared wavelength regions and low emissivity in the near infrared wavelength region. Such materials can include the class of materials known as Welsbach materials. The oxides of metal, e.g., aluminum oxide, are also suitable for the purpose. The greenhouse gases layer typically extends between about seven and thirteen kilometers above the earth's surface. The seeding of the stratosphere occurs within this layer. The particles suspended in the stratosphere as a result of the seeding provide a mechanism for converting the blackbody radiation emitted by the earth at near infrared wavelengths into radiation in the visible and far infrared wavelength so that this heat energy may be reradiated out into space, thereby reducing the global warming due to the greenhouse effect."
