Mechanism boundaries and physical plausibility

What happens to particles that carry little or no net charge?

A particle that carries little or no charge is still met by the media it passes through.

The filter captures airborne particles mechanically and by electrostatic attraction. NanoFlashing™ attracts negatively charged particles through electrostatic attraction. The Statement of Classification adds that the charge does not act on organisms only, and records that in single-pass laboratory testing the filter captured pine-needle smoke and ultrafine particles better than the control filter, and that smoke is neither a pest nor alive.

Capture by the charge and capture by the media are both part of what the filter does, and the company publishes no division of one from the other.
