Bests & Worsts Reviews from Amazon

I didn't see may reviews using it for mold, but decided to give it a shot. My attic (flat roof, ave height 21" with 15" fiberglass batt insulation) had bad mold smell from some roof leaks. The smell infiltrated into my 3rd floor and ductwork. Mold remediators said they had to take several air samples costing $800 before they'd give me an estimate. The usual solution was to rip down sheetrock and insulation, likely even in walls, and maybe rip out carpet and discard furniture. They they would treat attic, walls, etc. using air cleaners, hazmat suits, etc. Ach!! I ran the generator for 3 hr in each of 4 places in the attic, raising above insulation (ozone is heavier than air so place generator high). After the first one, the air smelled normal. I ran in the other 3 attic spots and in all the rooms on the 3rd floor. I turned off the AC so it wouldn't infiltrate the house, until the final treatment (to get the ducts). It's been about 2 weeks and the attic still smells fresh. It seems like the ozone goes thru painted sheetrock and down framing to some extent, based on odor (it smells). I tried to be careful about breathing ozone and left the house when it smelled strong. I did have a scratchy throat afterwards. I'm anxious to see if the mold was killed or if it grows back over time. I'll try to write an update in a month or so to say whether it did. The generator instructions don't say much about using it. I did a lot of research online to find out how. Ozone will kill mold if concentration is high enough for long enough. Ozone may damage plastic coating on wiring, plants, organic material like rubber (gaskets?) and oxidize metal. A corrosive expert told me he didn't think it would harm plastic flexduct. I don't see any damage on anything so far.
