Airthereal Commercial Ozone Generator

I've had five or six ozone machines over fifteen years. This one provides consistently the best performance. It can be run continuously--NOT recommended, by the way, except for extreme circumstances. But it stands up to abuse. It runs without complaint day after day. I have not yet replaced the ozone generator plate, it seems to be working fine. Ozone is like bleach gas. It's a very effective oxidizer, so it attacks odor-causing chemicals and the fungus/mold/bacteria that make the smells. FOR HOUSES/ROOMS: In our "barndominium", about 1700 square feet, I run it for 90 minutes when I leave. A week later when I come back, there's no funky smell or lingering mouldiness. Just fresh smell, almost like a thunderstorm just passed. FOR CARS: I let it run in a closed car, with the AC on max. The AC dries and circulates the air, and the ozone kills all those "interesting" car smells. It lasts for weeks or months sometimes. WARNINGS: 1) do not occupy the same space, and if you've just done it, air out the room/house/car before staying inside. The ozone numbs your sense of smell very quickly so it seems like it's gone, but it's damaging your lungs. It's very damaging to lungs. 2) ozone can damage some organic material; for instance, the rubber surrounding your window and door seals in your car. So I don't use it more than 3-4 times per year. I've never had trouble but I've read it can degrade soft rubber and foam. At the bardominium it's never damaged anything even though I've run it for hours at a time. OVERALL: Great product, and you can't beat de-odorizing with ozone!
