Where should ozone generator be placed?

Because ozone is heavier than air, an ozone generator should be placed at a high level in a room. Once the ozone has been dispersed, it will fall through the air. Air circulation is an important factor in how effective ozone works. An oscillating fan can be placed next to a generator for proper circulation.

The actual concentration of ozone produced by an ozone generator depends on many factors. Concentrations will be higher if a more powerful device or more than one device is used, if a device is placed in a small space rather than a large space, and if interior doors are closed rather than open. The proximity of a person to the ozone generating device also can affect one's exposure. The concentration is highest at the point where the ozone exits from the device, and generally decreases as one moves farther away.
