Moving air cools the skin. So to get the room-air moving well, a fan must push a moving column of air into the room.
The Australian consumer organisation Choice pitted the 2 Dysons against conventional pedestal fans. It measured 4 performance factors:
Each Dyson’s total volume of air was matched by only one of the conventional fans – and most of them delivered significantly less air.
The Dysons also pushed a very even flow of air well into the room. Most of the standard fans produced an intense flow near the fan but that dropped off quite rapidly as the distance from the fan increased.
The Dysons don't have external blades to move the air around; instead, the air's delivered through a patented "air multiplier" collar. They also have "continuously variable" speeds rather than the "set" speeds (low, medium and high) of most fans.
For efficiency and noise the Dysons were in the middle of the pack.
They do the job – but at $699 each, they’re also expensive.
