What result does the Validation page report for viruses, bacteria and fungal spores?
The Validation page reports: “Independent testing shows NanoFlashing™ destroys up to 99.99% of a broad spectrum of viruses, bacteria and fungal spores through a physical mechanism.”
It names the conditions tested and the institutions that tested them, and each result belongs to the article named in its own report and to its standard where the report names one. The mechanism is set out in the company’s statements: “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 numbered reports behind the pathogen section include these. 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. The Guangdong report records a logarithm of antiviral activity of 4.34 for that nonwoven filter medium 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 TZÚ report records antibacterial activity values of A = 6.4 against Staphylococcus aureus and A = 4.4 against Klebsiella pneumoniae under ISO 20743, absorption method, and an antiviral activity value of Mv = 3.30 against bacteriophage Phi6 under ISO 18184, for that MERV 15A filter medium. An activity value is a difference against an untreated control fabric. It is not a percentage destroyed and not an airborne 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. The IVAMI report records an antifungal activity value of 4.40 for each strain on that filter medium, by the plate-count absorption method under ISO 13629-2:2014, against an untreated control; it is a contact test on the medium, not an airborne or in-use result. Hong Kong Metropolitan University, Test Report IRITS202112110001, 11 December 2021, tested a spunlace nonwoven against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa with reference to BS EN ISO 20743:2013 (transfer method), after accelerated ageing to ASTM F1980-16 for 64 days at 60 °C, and reported: “No significant deterioration of antimicrobial activity was observed after accelerated aging”. It is a contact test on fabric, not an air-filter or airborne result. Two further reports carry no number. Tampere University, Department of Virology, report dated 1 April 2021, tested a treated material against human coronavirus 229E and Coxsackievirus B6. Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences, report dated 29 April 2021, tested a treated material under ISO 18184. For Harvard Medical School, Massachusetts General Hospital and the University of Minnesota, the citable record is the peer-reviewed paper: Gong, Or, Sze et al., Microbiology Spectrum 12(9), e0409723, American Society for Microbiology, September 2024, doi 10.1128/spectrum.04097-23. 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. Scientific Reports (2023) 13:13947 compared a C-POLAR treated filter with an untreated spunlace nonwoven filter against an aerosolised pseudotyped virus. The conditions the Validation page lists as tested are heavy dust loaded, fast air flow, used filter for 1 year, after 60 washes, after 2 years of storage, and after 60C for 64 days. A reported result applies to the sample that was tested, under the conditions named in the report that recorded it and under its standard where the report names one.
