Mechanism of action of the ACTIVE Particle Control system. Particulate pollutants, viruses, bacteria and allergens enter the conditioning phase and exit with a net-neutral charge. The technology-accelerated collisions result in particle agglomeration. The larger coagulated particles and their increased mass are subject to air currents that deliver the same to the collector media. Once collected, the highly defined high voltage field induces oxidative stress killing or inactivates any biological material.
