 It's a wonderful thing. These molecules even go behind and under furniture. Nothing can hide from the thunderstorm. And no filters to buy and replace over and over again. You can hold a thunderstorm in your hand. They're only this big, like this. And saves you money, saves you hassle. No filters. Come on. Right now, you can save $200 on an Eden Pure Thunderstorm 3-pack because you hang out with me. This is good for whole home protection.
