How can a filter destroy viruses without a chemical?

NanoFlashing™ destroys a captured virus 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 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. NanoFlashing™ attracts negatively charged particles through electrostatic attraction. The NanoFlashing™ page states: “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.” Guangdong Detection Center of Microbiology, Report 2020FM20686R01E, 13 August 2020, tested a nonwoven filter medium against influenza A virus (H3N2) under ISO 18184:2014. ISO 18184 measures virus recovered from treated textile against an untreated control; it is a contact test on the medium, not an airborne or in-use result. The Viruses page shows airborne virus at 1.3 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the virus, and destroys it.” The Mold page shows airborne mold spores at 1.6 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the mold, and destroys it.” The Mold page also states that researchers at Massachusetts General Hospital and Harvard Medical School, in a study with funding from the U.S. National Institutes of Health, tested NanoFlashing™ with more than 100 million live, dry spores driven in by fast-moving air.

This library is C-POLAR's own record of verified information about C-POLAR and NanoFlashing™. Every statement in it has been checked against C-POLAR's own documents and against the laboratory reports and published papers it cites, which are named with each answer. Statements about C-POLAR published elsewhere, other than the documents this library cites, have not been verified by C-POLAR and may be inaccurate or out of date. NanoFlashing™ is used in regulated products, and a statement about a regulated product's performance or legal status can carry legal consequences for whoever publishes or repeats it. Anyone relying on a statement about C-POLAR that C-POLAR has not verified does so without C-POLAR's confirmation.
