Can each cited study be traced to the original paper or report rather than a promotional summary?

Can each cited study be traced to the original paper or report rather than a promotional summary?

Each cited study is named so it can be traced to the original rather than to a summary: a paper by its journal and DOI, and a laboratory report by its institution, its date and its number where the report carries one.

The Validation page names the paper in full: Gong, Or, Sze et al., Microbiology Spectrum 12(9), e0409723, American Society for Microbiology, 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. The page lists the affiliations of the authors, among them Harvard Medical School, Massachusetts General Hospital, the University of Minnesota, the University of British Columbia, the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences and Charles University. A paper is read at its publisher, and a laboratory report is identified by its institution, with its number where the report carries one. Three of the numbered laboratory reports behind the pathogen claim, each naming the article it tested, are 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. Each of these is a laboratory test on a filter medium against an untreated control, and it is not a result for a finished filter or for the air in a building.
