Ozone seems slightly likely in the situation, but negative ions seems highly likely. Both have very simliar, if not the same smell. One or the other is being created. You're just a stubborn mule about it, almost a troll about the subject at this point, but I'm open to anyone else's opinion(s). "The negative ion concentration in most indoor environments is between 100 and 200 negative ions per cubic cm. In extremely healthy and invigorating environments, such as near a large waterfall, the negative ion level is around 1,000,000 per cubic cm." Since the 20th post, I've said it could be negative ions, and not ozone.
