Can a filter retrofit change the balance between supply and exhaust ventilation?
It can: the filter's resistance adds to the pressure the system's fan works against, and the label directs that it is not used where it would restrict airflow beyond the system's specification; what that means for the balance between supply and exhaust is settled by that system's own measurements, and the company does not publish a ventilation balance assessment.
This site publishes no fan curve, pressure-drop curve, motor load or duct data, and it does not model a particular system. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir. The label for the NanoFlashing™ Air Filter states a rated airflow and a maximum face velocity, and instructs: “Do not use where this filter would restrict airflow beyond the system's specification.” It also states: “Improper installation can reduce airflow or damage the equipment.” C-POLAR markets a materials technology.
