Does the C-POLAR website make health claims it cannot support?

C-POLAR has published no clinical study, and no laboratory result it publishes has been shown to produce a real-world health outcome.

A quotation on a page is the words of the person named with it: the home page quotes Prof. Michael K. Mansour, MD, PhD, Associate Professor of Medicine, Harvard Medical School, Division of Infectious Diseases, Massachusetts General Hospital, and names him with his words: “The utilization of NanoFlashing™ as an essential interrupter, breaking the chain of microbial spread, and reducing infections in multiple applications, results in improved overall health.” The published Terms of Use state: “A citation, quotation, name, logo, link, or third-party test does not by itself mean that the third party sponsors, endorses, certifies, or approves C-POLAR, a C-POLAR product, a Site claim, or a proposed use.” The Terms of Use state: “A laboratory reduction in a virus, bacterium, fungus, particle, or other endpoint does not establish a clinical benefit, fewer infections, disease prevention or treatment, or improved health.” 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. Its authors state: “Our findings have several limitations, including a need for clinical studies on nosocomial infections in hospital or healthcare settings.” The field observations on the Validation page are measurements of bioaerosols and particulates in hospitals, airports, banks and universities, made with MicronView’s 405 nm Bio-fluorescent Air Monitoring System, which distinguishes biological particles from inert dust in real time. A measurement of particles in the air is not a measurement of health. The label states: “It works alongside ventilation and cleaning, not in place of them.” For the air filter, the label states: “It is not a medical device and is not intended to diagnose, treat, cure or prevent disease.” The Terms of Use state: “As of the Effective Date, the Water, Textiles, Food packaging, and Medical devices chapters describe Research Applications. They do not describe finished products currently available from C-POLAR for those uses.”
