 The Eden Pure Thunderstorm is an air purifier, so it gets rid of pollen. It gets rid of dust. It also gets rid of those smells, tobacco smells, gunpowder smells from the Fourth of July, litter box smells, wet dog smells, cooking smells, you name it. You can plug it up with a USB cord. If you're in a car, it'll fire up and wipe out if someone smoked in the rental car and wipes out the odors. I've had to do that. Or a hotel room, I've had to do that. And it's small. You can hold it in your hand.
