Ozone reacts spontaneously with
terpenes to produce a hydroxyl radical (which will go on to react, terribly, with just about anything it can touch). It can also kill when used in a non ventilated area.
Ozone is an extremely potent oxidant. This is akin to walking around in a room of low ppm sulfuric acid vapors. You might be okay, but the shit is not healthy. Ozone can cause DNA damage and cancer, for you and your plants. The central oxygen atom of an ozone molecule carries a +1 charge. Oxygen DOES NOT want to carry a positive charge because it is very strongly electronegative (attracts electrons and thus, negative charge to itself--it stabilizes negative charges VERY well as a result). It is one of the most electronegative elements in the periodic table, in fact it is only surpassed by fluorine in this regard. That means this molecule will do ANYTHING to donate an oxygen atom across another bond. This results in the breaking of any bond the ozone touches basically. Yes it is effective at killing because of this and removing odor, but its also great at mutating cells, creating other carcinogenic compounds, and generally causing the destruction of anything it comes in contact with.
Frankly you shouldn't even be exhausting this stuff as it is VERY dangerous, and can be lethal in small amounts to asthmatics. Don't use it in a closed space under any circumstances.
Sulfur dioxide is about a million times safer to use--although still poses asphyxiation risk if you're silly. As an added benefit SO2 is available to your plant as a nutrient with uptake directly through the leaves.
Check: for why this might be important.
