While ozone is very powerful, it has a very short life cycle. When it is faced with odours, bacteria or viruses the extra atom of oxygen destroys them completely by oxidation. In so doing, that extra atom of oxygen is destroyed and there is nothing left ... no odour ... no bacteria ... no extra atom, only oxygen. In addition to ozones effectiveness, we also know that it is safe to use. We know this from our own safe exposures daily to ozone, weather, as noted earlier, resulting from being locked in traffic, or passing through industrial areas. These exposures have no effect on us beyond our acknowledging the unpleasant odour associated with this "filthy air". It is the very unpleasantness of this air that provides ozone with it's "built in" safety mechanism. Ozone is safe because we notice it's unpleasant odour at very residual levels. By residual we mean, the amount of ozone that is produced in excess of the required amount to kill whatever bacteria or odour that may be present in the room.

This equipment, when installed correctly will not exceed government guidelines for continuous safe exposure. Even if installed incorrectly, ozone provides its own protection, as ozone warns us in a manner similar to smoke in a room. Ozone does this by becoming so offensive at 1.5 parts per million that we would not be able to stay in the environment for any more than a short period. This is much like what would happen if we entered a smoke filled room.

However, while smoke might harm us, research has proven that such a limited exposure to such a low level of ozone would have no serous long term affect on us just as it does not affect us when caught in a traffic jam during rush hour. Carrying that example one step further, this equipment is incapable of producing ozone in sufficient quantities even if installed incorrectly and left running continuously, to cause any long term risks to your health even assuming that you could stand there and be exposed to it (remember the smoke example). Note that no one has ever claimed a worker's related illness resulting from ozone exposure.
