Set schedules and receive personalised air quality reports via the MyDyson™ app.⁷

The latest Dyson purifier features advanced purification technology that captures 50% more NO₂ – a common and potentially harmful household pollutant,³ produced by gas appliances, open flames, and wood-burning stoves.

It also features advanced detection, with a solid-state formaldehyde sensor that maintains accuracy throughout the purifier’s lifetime. It works alongside three other sensors to continuously monitor your air, interacting with our unique algorithm to diagnose and report pollutants in real time.

Three layers of purification deeply clean your air. HEPA H13 and K-Carbon filtration capture gases⁵, including NO₂, and 99.95% of pollutants as small as 0.1 microns.⁴ Our unique catalytic filter continuously destroys formaldehyde.⁶ And the entire purifier, not just the filtration system, is fully sealed to HEPA H13 standard⁴; so what goes inside stays inside.

Only Dyson purifiers feature Air Multiplier™ technology to purify the whole room.¹ It generates powerful circulation, drawing pollutants from all corners into the filters and projecting purified air throughout the room.

The latest Dyson purifiers are also compatible with smart home systems. The MyDyson™ app⁷ lets you control your indoor environment from anywhere, or hands-free via compatible voice services.⁸
