Abstract
A contaminant extraction apparatus, systems and method for extracting contaminants, such as particles and polar molecules, from an air flow containing a contaminated gas such as air so that the contaminants are expelled from the embodiments after they are extracted. One method includes the steps of generating two electric fields in separate air flow channels separated by an extraction grid with the second electric field having a greater potential difference than the first electric field; generating a first air flow through the first air flow channel and a second air flow through a second air flow channel; dispensing charged liquid droplets into the first air flow using at least one charged droplet generator; allowing the droplets to transfer charge to those contaminants; and expelling the contaminants into the second air flow using the potential difference in the second electric field.
