Scent Crusher claims that the ozone generator is expected to last 20 years. I wonder why there's only a 1yr warranty on it?
I like the sounds of that Scent Crusher "Ozone Go" unit that plugs into the truck and gets all the odors out of that too! Pet, food, gas (-oline AND farts ), cigarette smoke, wife's perfume, air fresheners, etc....! http://scentcrusher.com/ozone-go/
