 Dirty diapers and more are no match. The powerful thunderstorm sends out O3 molecules, which seek out and destroy odors. These molecules even go behind. And under furniture, nothing at all can hide from the thunderstorm. And best of all, no filters to buy over and over again. That saves you a bunch of money. Start taking care of your house again. Enjoy your home by getting several of these. You can save $200 on an Edencure Thunderstorm 3-pack for the entire home.
