 Now, I want to encourage you to go to EdenPureDeals.com. Why? Because you can get three Eden Pure Thunderstorms and save $200, and you get them for less than $200. The Eden Pure Thunderstorm is an air purifier, so it traps dust. It traps pollen. It traps the stuff floating in the air on electrostatic plates, no less, so you don't have to buy a subscription to keep getting filters.
