Can physical damage seen in an image establish loss of infectivity by itself?

Can physical damage seen in an image establish loss of infectivity by itself?

No. The company does not offer an image as proof that an organism has lost its infectivity.

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. 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 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.” They also state: “Images and descriptions may show concepts or prototypes. They are not specifications, instructions, validation reports, recommendations, warranties, offers, promises, or commitments.” The Validation page names the organisms tested and the institutions that tested them. An image is not the evidence. Each numbered report the company cites is named in text with its institution and number, not only shown in a picture.
