Has anyone measured what comes back off a used NanoFlashing filter into the air?

The company publishes no measurement of captured material coming back off a NanoFlashing™ filter into the air.

The company's position rests on the destruction of organisms held on the filter. 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. 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. The organisms were Staphylococcus aureus and Klebsiella pneumoniae under ISO 20743, and bacteriophage Phi6 under 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. Each is a contact test on the filter medium against an untreated control; it is not an airborne result, and it does not measure what leaves a filter in use. 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 Validation page also reports measurements in four buildings where NanoFlashing™ was installed. At a public hospital in Vancouver, two identical towers were compared, one on conventional medical grade filters and one on NanoFlashing™, and bioaerosols were measured at the NanoFlashing™ supply vent; the page says these were independently measured with MicronView's 405 nm Bio-fluorescent Air Monitoring System. Each is one building over one period, and it is not a result for another building.
