What Makes the difference is negative ions and fan speed control
HOW DOES THIS MODEL WORK?
The fan speed control (the knob with the blue end cap located on the back panel) adjusts the speed of the fan and will determine the amount of ozone and negative ions that are dispersed into any given area. Personal preference will determine the distance you wish the ozone and negative ions to be dispersed.
