But you must build and exchange box where ozone and contanmentated air have a chace to properly exchange ions before exuating. one other thing ther must be no moistior in this area becuase of cuastic nitric acid that will form. not good . Mabe build a box in your attic about 8' x 4' where you will have your ozone generater on a ppm controller with a timed exuast followed by a carbon scrubber. Ozone does have a wierd smell to it like after it rains. perfection. one last thing about is the heat it will produce in your attic. Not good for F.L.I.R. Mabe recerculate into house. just make sure you keep a deligent eye on your total ozone ppm return. It's not healthy.:jointsmile:
