Abstract: The present invention relates to a method and an apparatus for cleaning outside or inside air that is polluted by solid particles. The method comprises a specific sequence of measures for promoting agglomeration and/or coagulation of the particles, including ionization, followed by a series of filtrations. This lead to a surprising removal of ultra-fine particles of 1-100 μm with a great efficiency. The invention includes an apparatus for the application of the method.

Abstract: Systems and methods to remove dust from an extravehicular mobility unit (EMU) worn by an astronaut in a deep space environment involve one or more ionic shower units installed external to an interior volume of a facility. Each ionic shower unit releases positively charged ions and negatively charged ions in a specified direction to neutralize the dust and generate neutralized dust. The interior volume of the facility is defined by an interior hatch that is separated from an exterior hatch by an airlock. One or more collection units is installed external to the interior volume. Each collection unit traps the neutralized dust to prevent the dust from entering the interior volume.

Abstract: Disclosed is an apparatus and method for enhanced filtration. The apparatus utilizes a series of oppositely charged and opposing grids to condition incoming particles, promote conglomeration, and increase filtration efficiency. A filter media is positioned between two of the opposing grids. The grids opposing the media create an electrical field that polarizes the filter media and further increases filtration efficiencies. Still yet additional filtration efficiencies are realized by coating the filter media with a conductive polymer. The conductive polymer increases the associated dielectric constant to yield additional filtration efficiencies.
