Is there a recognized standard written specifically for a “destroys on contact” claim on a solid article, separate from filtration-efficiency standards?

Is there a recognized standard written specifically for a “destroys on contact” claim on a solid article, separate from filtration-efficiency standards?

The company names no single standard for a claim of destruction on contact; each contact test it cites is reported under its own standard, on a named medium, against an untreated control.

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. Guangdong Detection Center of Microbiology, Report 2020FM20686R01E, 13 August 2020, tested a nonwoven filter medium against influenza A virus (H3N2) under ISO 18184:2014. Textile Testing Institute – Brno (TZÚ), Test Report AZL 26/0757-02, 3 July 2026, a laboratory accredited to ISO/IEC 17025, tested a MERV 15A filter medium under ISO 20743 and ISO 18184. Instituto Valenciano de Microbiología, Report D/26/B0483, 6 August 2026, tested a VOLZ PROsyntex PLUS PM1 70 filter medium against Aspergillus brasiliensis and Aspergillus niger under ISO 13629-2:2014. Each is a contact test on the medium against an untreated control; it is not an airborne result and not a result for a finished filter in a building. 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. ASHRAE 52.2 and ISO 16890, the standards named for the Validation page's air-filtration ratings, measure what a filter takes out of the air, and they say nothing about what happens to what is captured.
