Are claims narrowed when the feasible product differs from the original research concept?

Each numbered report the company cites is named with its institution and number, and a result covers only the article and the conditions that report names.

The Validation page names what was tested, the conditions and the institutions, and it gives report and certificate numbers for the air-filtration, certification and safety records, including LMS Technologies, Report LMS#9904, 28 April 2025, a single-pass fractional efficiency test on a 24 × 24 × 2 in. pleated air filter in an ASHRAE 52.2 test duct, in accordance with standard LMS aerosol test procedures, and Report 6847, ASHRAE 52.2 with Appendix J, Eurovent Certita Certification, Certificate No. 15.06.011, OEKO-TEX Service GmbH, Certificate 17.0.25812, Product Safety Labs, Studies 65321 to 65324, and Intertek Building & Construction, Report 105175501SAT-001. Report 6847 covers a 24 × 24 × 30 in. pocket filter and Certificate No. 15.06.011 a ten-pocket bag filter, not a flat panel filter, and a rating belongs to the construction that was tested and to the conditions in the report. The Terms of Use state: “A reported result describes only what the identified test found.”

A capture standard is not a destruction standard: ASHRAE 52.2 and ISO 16890 measure what a filter takes out of the air, and they say nothing about what happens to what is captured. The company's statement on destruction is its own. 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. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory.
