Which bacteria does the Validation page list as tested?

The Validation page lists five bacteria as tested: Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis.

The numbered reports the company can cite for bacteria include these. 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 antibacterial results are against Staphylococcus aureus and Klebsiella pneumoniae under ISO 20743. 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. The Open University of Hong Kong, Test Report IRITS2020007030001R1, 7 June 2021, measured bacterial filtration efficiency on a spunlace nonwoven by a method modified from ASTM F2101:2019, after accelerated ageing to ASTM F1980-16 equivalent to five years at room temperature. Bacterial filtration efficiency is a measure of capture, not of destruction. The peer-reviewed paper is 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. 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.
