Are findings for a harmless test surrogate identified as surrogate evidence?

The company names each organism tested, including Phi6 bacteriophage, bovine coronavirus and pseudo-type SARS-CoV-2, and it does not label any of them as standing in for another.

The core science is peer-reviewed and published: Gong, Or, Sze et al., Microbiology Spectrum 12(9), e0409723, American Society for Microbiology, co-authored by 31 scientists from 18 research institutions. On the Validation page the viruses are SARS-CoV-2, human coronavirus 229E, Coxsackievirus B6, bovine coronavirus, pseudo-type SARS-CoV-2, influenza A H3N2 and Phi6 bacteriophage; the bacteria are Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis; the fungi are Aspergillus fumigatus, Aspergillus brasiliensis, Aspergillus niger and Candida albicans. 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. Its virus result is against bacteriophage Phi6 under ISO 18184. A published paper, Scientific Reports (2023) 13:13947, compared a C-POLAR treated filter with an untreated spunlace nonwoven filter against an aerosolised pseudotyped virus. 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 Terms of Use state: “A reported result describes only what the identified test found.” The test article, the organism, the method, the control, the conditions, the contact time, the sample and the endpoint identified in a report are the limits of what that report shows. 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.
