Does a pooled figure hide a poorly performing product variant?

Does a pooled figure hide a poorly performing product variant?

The company publishes no pooled analysis across product variants.

A result covers the samples it was measured on.

The Terms of Use state: “A reported result describes only what the identified test found.” They also 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.” A laboratory report describes what that test found on the article tested; it does not establish performance in a building, over a service life, or under conditions it did not test. One laboratory and its subcontractor can issue several documents about one test, so a count of documents is not a weight of evidence. 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.

What can be checked on any filter is the charge. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
