Bests & Worsts Reviews from Amazon

After using the product for long enough that I thought I was happy with it, and threw the packaging away, I developed a massive headache that nothing would touch for hours- ibuprofen, tylenol, ibuprofen on top of tylenol, etc, I left my house to run some errands, and miraculously, the headache went away. Remembering some reviews that I had read on this site about the purifier causing headaches, I unplugged it when I got home, and haven't had a headache since. Mentioning it to my husband, he said that ionizers can produce ozone, and some people are sensitive to it. I guess that's me. I wish there were some kind of warning on the site about it, because I wouldn't have bought the purifier if I had known that was a possibility. $150 down the tube. I'm not happy at all.
