Dyson advertises that this fan moves 5 gallons per second of air. That translates to 40 cubic feet per minute. This is how fans are typically specified. But Dyson won't use those units of measurement, because that would allow you to make the comparison yourself and realize just what a lousy air mover this fan is.
To put this into perspective, a small clip-on 6" fan can move 190 cubic feet per minute. That little fan costs about $20.
Dyson achieves this deception through props - typically streamers placed around the edge of the fan in store displays and ads. Sure, the air does move quickly from the edge of the fan, just as fast as it moves from conventional fans. However, this is only a thin ring of air movement in the case of the Dyson fans - versus a full circle of air movement from a conventional fan. This helps to explain the difference in air moving performance.
Conventional fans are also quieter. Again, that little 6" clip-on is only 37 decibels. The Dyson is 50 decibels.
The Dyson fan is beautiful and safe. But as a fan, it is loud, has terrible air flow, and is preposterously overpriced other than as a work of art.
Better to buy a fan that works and some artwork that isn't masquerading as a fan.

A table fan that quietly and effectively cools an entire room without any blades? Introducing the Dyson Air Multiplier, which works differently from conventional fans. The Air Multiplier uses an airfoil-shaped ramp to amplify the airflow 15 to 18 times to create a cool blast of smooth air without the unpleasant buffeting caused by spinning blades. The energy-efficient motor draws in more than 5 gallons of air per second using the same technologies used in jet engines. The air passes over the airfoil-shaped ramp, which channels its direction. Air behind and around the machine is also drawn into the airflow, amplifying it at least 15 times for a quiet, cool breeze that will let you relax. With no blades or grille to get in the way, the Air Multiplier is safe around kids and pets, and it\'s easy to clean too. The touch-tilt feature pivots on its own center of gravity, letting it stay put without clamping. You can also adjust the airflow to get as much as you want. There\'s no "high," "medium," or "low"; the dimmer switch lets you set the exact power level you want. The Air Multiplier oscillates with a touch up to 90 degrees to cover a whole room. Includes base, loop amplifier, and operating manual. 2-year warranty. Measures 21.5 x 14 x 6 inches with 12-inch loop.
