Is measurement uncertainty large enough to change the conclusion about charge retention?
The company publishes no uncertainty figure, so there is nothing to weigh against a conclusion.
The polarity is a positive electric charge at rest, and it is measured as surface charge density, in nanocoulombs per square centimetre. What the company states about permanence is the property itself and the NanoFlashing page's statement: “NanoFlashing™ does not fade.” NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The company publishes no measurement procedure, no instrument record and no uncertainty budget. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
