ozone is deadly, dangerous, and poisonous. i cant really use any other words to describe it. anyone who knows about chemistry knows that O3 has a free radical. its not real nice to have around anything. its unstable. its bad. at high concentrations or low.

just depends on the scale of the object of its affections. if you just start pumping ozone into a bag or something, its really nice. just store that bag for a while and the O3 will decompose into O2. nice O2 source.
a tiny amount will do a good job at killing airborne contaminates and if you can afford to replace the housing of where ever you keep the ozone, its a good tool to use.

just use it correctly. do a couple huffs of a low concentration or just sit in the room for a while if you dont believe me. and btw, the best source of info on safety of a product is usually not the company who makes one.
