Abstract
An air filtration system uses a liquid to remove impurities from the air. A specialized chamber allows the air and liquid to contact each other in close proximity, so that the liquid can pick up not only particulate matter, but fumes and toxic gasses as well. The air can be bubbled through the liquid, or the liquid can be introduced into the chamber as a gentle rain, a spray, a vapor, a waterfall, or any other configuration that allows active contact between the two mediums. The liquid can then be cleaned of contaminants, e.g., by centrifugal force, while the liquid is then reused.
