 Any smell will vanish after just a few seconds with the thunderstorm being on. Odors from litter boxes, trash cans, cigarettes, smoke, dirty diapers, even left-wing activists. No match for the Eden Pier thunderstorm. The powerful thunderstorm sends out O3 molecules, and they seek out and help destroy odors. These molecules even go behind and under furniture because nothing can hide from the thunderstorm. And best of all, no filters to buy and replace over and over again.
