Cooler air is more dense than surrounding air, and thus falls in an inverted plume over the breathing zone (blue arrows), thereby displacing airborne particles traveling into the breathing zone (red arrows) into a more peripheral location. This is a schematic, to aid understanding of the principles of TLA treatment. It does not represent the full complexity of air currents in the home; for example, air entrained into the overhead inverted plume is not shown.
