# C-POLAR Source: https://cpolar.tech/ C-POLAR is the health science company behind patented NanoFlashing™ technology, which gives everyday products permanent positive polarity. The world already makes the products. NanoFlashing™ changes what those products can do. One Technology. Five Primary Application Verticals: Air, Water, Textiles, Food, Medical. This is the text of that page, in a form a machine can read. Nothing in it is paraphrased or shortened. After it come short extracts from other C-POLAR pages, each quoted word for word with the page it comes from. --- [Skip to main content](#main) [Science](/nanoflashing/) [Applications](/air/) [About C-POLAR](/about/) [Contact Us](/contact/) - [Home](/) - [Science](/nanoflashing/) - [Applications](/air/) - [About C-POLAR](/about/) - [Contact Us](/contact/) - [Validation](/validation/) - [Privacy Policy](/privacy/) - [Terms of Use](/terms/) ## The Future of Protection How a new class of technology could help redesign the products the world depends on. One technology. Limitless impact. Positive ChargeProton Negative ChargeElectron Cloud Positive SideFewer Electrons Negative SideMore Electrons Lighter AtomExposed Proton Heavier AtomStronger Pull Shifted Electron CloudDrawn Toward the Heavier Atom Physical Positive Polarity Negative Charged Pollutant Step 1 — Inside every atom, protons carry a positive charge and electrons carry a negative charge. Step 2 — When a heavier atom joins a lighter atom, they share electrons. The heavier atom in this pair has a stronger pull on the shared electrons, drawing them away from the lighter atom and closer to itself. Step 3 — 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. Step 4 — 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. This is a physical property. NanoFlashing™ is passive. It generates no ozone, releases nothing, and adds nothing to what passes through. Step 5 — 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. Step 6 — 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. Attract. Capture. Destroy. ### How NanoFlashing™ Works ### Many airborne particles carry an electric charge.

The NanoFlashing filter is a device, not a disinfectant. The bacteria tested cover both groups EPA uses to define broad spectrum: Gram-positive (Staphylococcus aureus, Enterococcus faecalis) and Gram-negative (Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli). The viruses include Coxsackievirus B6, a Picornaviridae virus. EPA lists that family in its small, non-enveloped group and says: "These small, non-enveloped viruses can be highly resistant to inactivation by disinfection." (https://www.epa.gov/sites/default/files/2016-09/documents/emerging_viral_pathogen_program_guidance_final_8_19_16_001_0.pdf). The viruses also include SARS-CoV-2 and influenza A H3N2.

Reg. 51065 (19 November 1976), records that devices subject to FIFRA sections 2(q)(1) and 7 include, but are not limited to, “certain ultraviolet light systems, ozone generators, water filters and air filters (except those containing substances or mixtures of substances which are pesticides), and ultrasonic devices, for which claims are made to kill, inactivate, entrap, or suppress the growth of fungi, bacteria, or viruses in various sites”. That exclusion takes out air filters containing a substance or mixture of substances which is a pesticide. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. A charge is a physical property. It is not a substance or a mixture of substances. The NanoFlashing™ Air Filter incorporates no substance or mixture of substances to perform its intended pesticidal purpose, it has not been treated with a biocidal product and does not incorporate one, and it is not sold or packaged with any pesticide. > > A device is not required to be registered under FIFRA section 3, so selling an air filter that is a device without an EPA registration does not break that requirement. C-POLAR classifies the NanoFlashing™ Air Filter as a device, not an antimicrobial treatment, under the definition at 40 C.F.R. § 152.500(a), and EPA states a device works solely by physical means. > > The company classifies the NanoFlashing™ Air Filter as a device under Section 2(h) of FIFRA, not as a pesticide. Section 2(u) defines a pesticide as “any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest”. 40 C.F.R. § 152.500(a) defines a device as “any instrument or contrivance (other than a firearm) intended for trapping, destroying, repelling, or mitigating any pest or any other form of plant or animal life (other than man and other than a bacterium, virus, or other microorganism on or in living man or living animals) but not including equipment used for the application of pesticides (such as tamper-resistant bait boxes for rodenticides) when sold separately therefrom.” > > A pesticidal device under FIFRA is an instrument or contrivance intended for trapping, destroying, repelling or mitigating a pest, which works solely by physical means and incorporates no substance or mixture of substances to do it. EPA states the test in its own words: “A device must work solely by physical means (such as electricity, light or mechanics).” That sentence is EPA’s published interpretation in Compliance Advisory 305F20004 (October 2020); the definition itself is at FIFRA section 2(h), 7 U.S.C. § 136(h), and 40 C.F.R. § 152.500(a). > > EPA states in Chapter 13 of its Pesticide Registration Manual that “EPA establishment numbers, which are required for devices, are not the same as EPA pesticide registration numbers required for pesticide products”, and that “Obtaining an establishment number is an administrative process, completed upon request to the EPA.” Source: https://cpolar.tech/reference/us-regulatory-status/ > - 40 C.F.R. § 152.500, [https://www.ecfr.gov/current/title-40/chapter-I/subchapter-E/part-152/subpart-Z/section-152.500](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-E/part-152/subpart-Z/section-152.500) > - EPA, Pesticide Registration Manual, Chapter 13: Devices, [https://www.epa.gov/pesticide-registration/pesticide-registration-manual-chapter-13-devices](https://www.epa.gov/pesticide-registration/pesticide-registration-manual-chapter-13-devices) > - EPA, Pest Control Devices and Device Producers, 41 Fed.
