So there is still controversy regarding ozone generators. The author says the interviewee says they should not be used.
My problem is that there is a high count of mold in the air here. Seems like that is true every day all year. I have an air purifier, which works with high heat (400F) only. Small chamber uses 50 watts to heat passively rising air high enough to kill mold, dust mites, and other nasties. I have another that uses a hepa filter as well as ultraviolet light. But still, I do have to go outside after all. And it is not easy or healthy to keep the house closed up all the time.
