Dyson’s first ever hairdryer is safer and easier to use

The maker of the first bladeless fan and bag-less vacuum cleaner, Dyson Technologies' first ever hair dryer, the Dyson Supersonic, is an expensive, lightweight device designed to prevent heat damage to users' hair.

The device combines a number of design elements from Dyson's previous gadgets, including the "air multiplier" technology from its bladeless fans and the industrial stylings and digital motors of its handheld vacuum cleaners.

The Supersonic, priced at £299, is at the upper-end of the personal care appliances market.

It was earlier rumoured that the Supersonic was noiseless, which is not true, but it is pretty silent; Dyson points out that it is impossible to blow air through channels at high speeds without making a noise.

The engineers at Dyson tuned the acoustics of the Supersonic's digital motor to cut down the noise to a minimum, and increased the number of blades on its rotor from 11 to 13 to modulate one of the vibrating tones to a frequency inaudible to human ears.

While in real life use it is possible to have a normal conversation when the Supersonic is set to the lowest of three airflow settings, but at full blast one would need to raise one's voice to be heard.

The Supersonic comes with a thermostat that  measures air temperature 20 times a second to keep the temperature consistent so users need not worry about overheated air burning their hair.

It also features a built-in ioniser to deionise hair, which effectively cuts down on static electricity.

However, the most startling feature of the device is, as Dyson claims, it blows air at least twice as fast as the average blow dryer.

The hairdryer comes with a tiny motor which can also can fight off hair clogs, that are anyway not likely to happen, thanks to two filters and the unusual design.

The tiny motor has a little notch, right next to the impeller blades and if any hair were to find its way that far, it got chopped to bits between the notch and the blades.
