I have an Enaly OZX-A200 Ozone Air Purifier -- an ozone generator hanging in my garage:
Ebay for $119.
It was being used with a UVnair 3500 in the attic. The UVnair burnt out, so I thought I would try a Organic Air Charcoal Fiber Filter. I could not get any reviews on it so I will be the tester I guess.
