Plug-in odor eaters aren’t new; you've likely seen them in the household goods aisle of your local grocery store. But the innovative GermGuardian doesn’t merely fight odors. In fact, by leveraging the power of UV-C light technology, the device also works to kill airborne germs, reducing or eliminating the ability of fungi, bacteria, and viruses to develop and proliferate throughout your home. How does it work? Don't worry—there’s no assembly or setup required. Simply place the GermGuardian into any area of concern—the bathroom, perhaps, or the nursery—and leave it to do the dirty work of sanitizing the air you breathe on a daily basis. Available at Amazon; $37.
