It took a team of 68 designers three years and 640 prototypes to create the Dyson Cool AM06, an update to the company's revolutionary Air Multiplier. The 10-setting, bladeless fan is as powerful as the original, drawing in air through its base and channeling it in steady jets. Thanks to a reengineered motor, however, the Cool is 75 percent quieter.
