Is an observed surface effect reversible when the surrounding conditions change?
The polarity is described as permanent, and what is measured is surface charge density.
The charge is measured on every production run, and the measurement can be repeated on any filter, upon request. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. A reported result applies to the sample that was tested, under the conditions and the standard named in the report that recorded it.
NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter.
