A result belongs to the article that was tested.

The records named on the Validation page are on different articles. Eurovent Certita Certification, Certificate No. 15.06.011 under ISO 16890, and the MERV 15A result under ASHRAE testing, are on pocket and bag filters. Intertek Building & Construction, Report 105175501SAT-001 under UL 900, is on a panel filter, and Report 104974202SAT-001 on a bag filter. The company's label and its Statement of Classification describe a panel air filter for forced-air heating, ventilation and air-conditioning systems. A rating applies to the filter that was tested, not to every product that carries the technology. The numbered reports on the pathogen testing of filter media are 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. 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. Guangdong Detection Center of Microbiology, Report 2020FM20686R01E, 13 August 2020, tested a nonwoven filter medium against influenza A virus (H3N2) under ISO 18184:2014. Each is a contact test on the medium against an untreated control, not an airborne result and not a result for a finished filter in a building. The Viruses page shows airborne virus at 1.3 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the virus, and destroys it.” The Mold page shows airborne mold spores at 1.6 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the mold, and destroys it.” The Mold page also states that researchers at Massachusetts General Hospital and Harvard Medical School, in a study with funding from the U.S. National Institutes of Health, tested NanoFlashing™ with more than 100 million live, dry spores driven in by fast-moving air.

The Terms of Use state: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it. Construction, processing, storage, wear, cleaning, other components, and actual use may change the result.” They also state: “Use evidence, specifications, instructions, and warnings specific to the actual finished product and use.” A copy may be made available on our review of the request. Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory.
