NanoFlashing™

What is NanoFlashing™?

NanoFlashing™ is a patented permanent positive polarity (3P) technology that attracts and captures negatively charged pollutants, including PFAS, ultrafine particles, wildfire smoke, and pollen.

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. Many airborne particles carry an electric charge, and many are negatively charged. NanoFlashing™ attracts negatively charged particles through electrostatic attraction. Once attracted, the particle is captured by NanoFlashing™. When a captured pollutant has a fragile structure, NanoFlashing™ destroys it on contact through a physical mechanism. NanoFlashing™ is passive. It generates no ozone, releases nothing, and adds nothing to what passes through.

What is the active ingredient in NanoFlashing™?

The term “active ingredient” belongs to pesticide registration, not to the company's description of NanoFlashing™: C-POLAR describes a charge, and states that the filter incorporates no substance or mixture of substances to perform its intended pesticidal purpose.

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 filter captures airborne particles mechanically and by electrostatic attraction. The filter is intended to destroy the viruses, bacteria and fungal spores it captures. It destroys them on direct contact with the positive electric charge, by physical means, and only while the organism is captured by the positive electric charge. NanoFlashing™ is passive. It generates no ozone, releases nothing, and adds nothing to what passes through. The company classifies the NanoFlashing™ Air Filter as a device under Section 2(h) of FIFRA, 7 U.S.C. § 136(h), and 40 C.F.R. § 152.500(a), and its Statement of Regulatory Status under European Union law states: “It contains no active substance.” The company does not publish the composition of the media.

How does the published description distinguish polarity from a chemical reaction?

The published description calls polarity a physical property and says it does not rely on a chemical reaction.

The account on the NanoFlashing page runs in steps. Inside every atom, protons carry a positive charge and electrons carry a negative charge. When a heavier atom joins a lighter atom, they share electrons, and the heavier atom has a stronger pull on the shared electrons, drawing them away from the lighter atom and closer to itself. This uneven sharing creates a negative side and a positive side. This is called polarity. Polarity is a physical property, like density or weight. It is built into the molecular structure and does not rely on a chemical reaction. In NanoFlashing™, these molecular pairs are aligned in the same direction, with their positive sides facing outward and their negative sides tucked inside. Together, they create a permanent positive polarity.

A charge is a physical property. It is not a substance or a mixture of substances. The polarity is a positive electric charge at rest.

How does NanoFlashing™ attract negatively charged particles?

NanoFlashing™ attracts negatively charged particles through electrostatic attraction.

Many airborne particles carry an electric charge, and many are negatively charged. Like a magnet, the positive polarity of NanoFlashing™ attracts negatively charged particles through electrostatic attraction. The filter captures airborne particles mechanically and by electrostatic attraction. The charge does not act on organisms only: in single-pass laboratory testing the filter captured pine-needle smoke and ultrafine particles better than the control filter, and smoke is neither a pest nor alive.

The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir.

What does the description say happens after a pollutant is captured?

Once attracted, the particle is captured by NanoFlashing™, and when a captured pollutant has a fragile structure, NanoFlashing™ destroys it on contact through a physical mechanism.

The company's fuller statement of the same thing is in its Statement of Classification, at 2.6: “The filter is intended to destroy the viruses, bacteria and fungal spores it captures. It destroys them on direct contact with the positive electric charge, by physical means, and only while the organism is captured by the positive electric charge.” Intended, on direct contact, by physical means, and only while captured are the limits of that statement.

What does the published description say about ozone and releases?

NanoFlashing™ is passive. It generates no ozone, releases nothing, and adds nothing to what passes through.

The NanoFlashing page states it twice, at step 4 of the account and again under Permanent Positive Polarity: it generates no ozone and adds nothing to what passes through. The Statement of Classification states at 2.4 that in use the ventilation system's own fan moves air through the filter, that the filter is passive, that it draws no power and has no power supply, electrode, lamp or reservoir, that it generates no ozone and emits nothing into the air passing through it, and that the air leaving the filter has had nothing added to it.

That is a statement about what the filter gives off. The company makes no claim about removing ozone from air that already carries it.

Does the published description call NanoFlashing™ passive?

Yes.

The published description calls NanoFlashing™ passive, in those words.

The NanoFlashing page states: “NanoFlashing™ is passive.

The Statement of Classification states at 2.4 that the filter is passive, that it draws no power, and that it has no power supply, electrode, lamp or reservoir, and that the ventilation system's own fan moves the air through it.

The label for the NanoFlashing™ Air Filter states that no power is required and that there is no by-product such as ozone. A complete air cleaner still has to move air, and the fan that does it belongs to the appliance or to the building's system.

How does the Air page describe the filter's permanent positive polarity?

The Air page says the NanoFlashing™ Air Filter has a permanent positive polarity, a fixed positive charge.

It states that the filter attracts and captures ultrafine particles and wildfire smoke, with no power and no chemicals. The company's own statement of the same property is that NanoFlashing™ is a permanent positive polarity engineered into filter media itself, that it is a physical property of the filter, and that the polarity is a positive electric charge at rest. Its statement of what the filter does to what it captures is the one at section 2.6 of the Statement of Classification: “The filter is intended to destroy the viruses, bacteria and fungal spores it captures. It destroys them on direct contact with the positive electric charge, by physical means, and only while the organism is captured by the positive electric charge.”

The Air page also names the two products built on that filter: INHALO™, a wall-mounted air cleaner built around a NanoFlashing™ Air Filter, and ReinFire™, a NanoFlashing™ Air Filter for homes and buildings.

What evidence supports the published explanation of how the permanent polarity is created?

What the company measures is the charge itself.

The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request. The NanoFlashing manufacturing process produces the charge. The process acts on the filter by physical means. The science behind NanoFlashing™ was reviewed by other scientists and published by the American Society for Microbiology: Gong, Or, Sze et al., Microbiology Spectrum 12(9), e0409723, American Society for Microbiology, September 2024, doi 10.1128/spectrum.04097-23. That article is the authors' publication of the science, and the company does not present it as a measurement of the charge. The published step-by-step account of polarity is the company's description of the physical principle; the thing that is measured is the surface charge density. The paper reports laboratory results on SARS-CoV-2 in contact with treated textile, on aerosolised bovine coronavirus passed through a test filter in a wind tunnel, and on bacterial viability on treated textiles; each result belongs to the article that was tested.
