Is NanoFlashing just a coating?

C-POLAR describes NanoFlashing™ as a physical property of the filter, and its Air page states that the NanoFlashing™ Air Filter works “through a physical mechanism, with no power and no chemicals.”

NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. A charge is a physical property. It is not a substance or a mixture of substances. The NanoFlashing manufacturing process produces the charge. The process acts on the filter by physical means. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request. The NanoFlashing™ page states: “Polarity is a physical property, like density or weight. It is built into the molecular structure and does not rely on a chemical reaction.” A research paper or a patent records its authors' work in their own words, as it stood when it was written. The company's description of the product it sells is the one in its Statement of Classification and on its website. NanoFlashing™ is patented, and the company does not publish the composition of the media or the particulars of the process.
