Can any claim about permanence be reconciled with the documented end-of-life properties of the material?
Permanence describes the property in the media, and the label sets when the article is replaced.
NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request. The label directs that the filter be replaced at the pressure drop or the interval printed on it, whichever comes first. The NanoFlashing page states: “NanoFlashing™ does not fade.” Hong Kong Metropolitan University, Test Report IRITS202112110001, 11 December 2021, tested a spunlace nonwoven against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa with reference to BS EN ISO 20743:2013 (transfer method), after accelerated ageing to ASTM F1980-16 for 64 days at 60 °C, and reported: “No significant deterioration of antimicrobial activity was observed after accelerated aging”. It is a contact test on fabric, not an air-filter or airborne result.
