Naturally, the new product tries to dovetail in the company's know-how from other families: Dyson's folded in its air multiplier technology too (making the design pretty similar to its fan), expanding the range compared to rival humidifiers. Perhaps unsurprisingly, it also doubles-up as a fan in the summer. The air itself is also measured by an intelligent thermostat, keeping the air "comfortable", according to Dyson's Tom Bennett, and consistently adjusting its output accordingly. There's a three-liter tank, which can apparently ensure 18 hours of air-based moisture. It's beneath this reservoir (where the water mills around) that the UV light does its trick, squashing bacteria inside before it's taken up and sprayed as a mist across the room. It's also qualified for the "quiet mark" in the UK, benefited from Dyson's acoustic know-how. It barely makes a hiss. There's no word on roll-out outside of Japan just yet, but it looks like Dyson is working to ensure all that R&D pays off.
