Dyson's latest purifiers combine intelligent sensing with an advanced filtration system. Three phases of purification sit within a fully sealed filtration and airflow system. So what goes inside, stays inside. A solid-state formaldehyde sensor and a unique catalytic filter detect and continuously destroy formaldehyde. Then powerful Air Multiplier technology purifies, heats the whole room and cools you.

Third party full machine testing based on GB/T formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.

Tested In maximum setting for air projection, tested in Auto mode for purification coverage, tested for room heating per relevant Dyson method DTM961.

Requires device to run app, Wi-Fi or mobile data, Bluetooth 4.0 support, and iOS version 10 or Android version 5 (or above). Standard data and messaging rates may apply. Refer to the MyDyson app for compatible voice services.
