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.⁶ A solid-state formaldehyde sensor and a unique catalytic filter detect and continuously destroy formaldehyde.¹ Then powerful Air Multiplier™ technology purifies, heats the whole room and cools you.²
