I noticed the downstairs bathroom where I ran it for 20 minutes there is no black mold growth in the toilet after a week like before. I think it killed every nearby living thing.I bought this one too and 10 minutes in a bathroom eliminates all musty odors from steamy showers. I tried 20 minutes and smelled ozone for 3 days.
It is too much for home use unless you like power.
