Ozone Generator Any experince with this model (pics)

Ok, so I have been researching a small generator for a room that only about 5x5x8. I was wondering if anyone has ever tried using one of these? Will it work to kill the smell? Ideas?

Yes, that thread is actually the one that got me to start looking at these. I have a small area in a parents house that I want to cover the smell. However, in this small area where would I put something like that? Isn't it harmful to me and my plants in a 5x5x8 room? The same company makes a smaller one also that is good for upto 1000cf and I was looking at that one too. HELP GUYS!!! Thanks for everything.
