20140076163 | System for Filtering Airborne Particles - Disclosed is a system for filtering airborne particles from an occupied space. The system permits the removal of airborne particles by manipulating both the charge and the size of the particles, thus enabling the capture of particles that most other typical filtration systems leave behind. More specifically, the system captures small airborne particles through the use of a series of electric fields, forcing them to be trapped in a series of filters or collide to form larger particles, whereby their movement and capture are subsequently governed primarily by airflow. The system controls particle behavior by utilizing specific electromagnetic fields to collide particles, capture particles, and deactivate live pathogens that get captured. | 03-20-2014 |
