# NanoFlashing™ | C-POLAR Source: https://cpolar.tech/nanoflashing/ How the NanoFlashing™ polarity attracts, captures and destroys, and why the charge does not fade. 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 the content](#what-it-is) ## Discover NanoFlashing™ ### Permanent Positive Polarity (3P) NanoFlashing™ is a patented permanent positive polarity (3P) technology that attracts and captures negatively charged pollutants, including PFAS, ultrafine particles, wildfire smoke, and pollen. It captures and destroys up to 99.99% of a broad spectrum of viruses, bacteria, and fungal spores through a physical mechanism. It generates no ozone and adds nothing to what passes through. 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 ### It does not fade. Conventional electrostatic charges fade in service, dragging performance down with them. An EPA study shows that just 10 milligrams of smoke can cut a conventional MERV 13 electrostatic filter’s clean-air delivery by [about 95%](https://pmc.ncbi.nlm.nih.gov/articles/PMC9828579/). During the 2025 Los Angeles wildfires, a typical home system could take in that much smoke in roughly two minutes. NanoFlashing™ does not fade. Independent testing pushed 100x more smoke through filters than in the EPA study. These filters still captured > 90% of ultrafine particles, while a conventional electrostatic filter captured < 20%. These particles are small enough to penetrate deep into the lungs, and some can enter the bloodstream. ### We change what products can do.

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.
