The fan had remained unchanged for over 100 years. Conventional fans are inefficient and chop the air. They can be difficult to clean, noisy, and have a high centre of gravity – making them prone to falling over.
Air Multiplier technology gives an uninterrupted stream of air - no choppy airflow. With its simple loop the fan is quickly wiped clean with a cloth. Fans with blades are nigh on impossible to clean, with dust and dirt building up inside the cage.  The same dust and dirt is then billowed into your face when the fan is switched on.
Unlike top-heavy conventional fans, Dyson bladeless fans have an energy-efficient motor in the base, meaning they have a low centre of gravity and won’t topple over.  You have to use two hands to position a fan with blades. The Dyson Air Multiplier fan adjusts easily with the touch of the hand.  It pivots on its low centre of gravity and stays put.
