This Dyson runs hot and cold – literally. With a flick of the a switch, this bladeless fan goes from offering a cooling zephyr to a warming breeze. Genius! But even better, the Dyson AM09 Hot+Cool’s bladelessness means it runs in near-silence, so you can say goodbye to your frankly worrying assortment of fans and blowers that sound like so many faltering helicopters. Also, there are no blades to dust and no visible heating element. $699, from major appliance retailers.
