I saw this air multiplier fan on YouTube, and I didn’t believe it! But it is true! This fan is a bladeless fan, that is to say there is absolutely no blades! The Dyson Air Multiplier™ fan works very differently to conventional fans. It uses Air Multiplier™ technology to draw in air and amplify it 15 times, producing an uninterrupted stream of smooth air. With no blades or grill, it’s safe, easy to clean and doesn’t cause unpleasant buffeting. The one big issue is that it is very expensive, it costs around $400 each!
