Abstract
An air cleaner including a corona wire assembly, a power supply electrically connected to the corona wire assembly, a fan to draw air through the air cleaner, a fan speed control, and a controller to sense the fan speed and control the power supply, such that an amplitude of a current provided by the power supply to the corona wire assembly is proportional to the fan speed is described. By varying the corona wire assembly current proportionally with the fan speed, the ozone output is minimized at all speeds. So as fan speed decreases, the current supplied to a corona wire assembly decreases, thereby reducing the ozone generated by the air cleaner.
