Dyson Formaldehyde HP09 Air Purifier and Fan

Dyson's latest purifiers combine intelligent sensing with an advanced filtration system. The purifier features three phases of purification within a fully sealed filtration and airflow system, ensuring that what goes inside, stays inside. A solid-state formaldehyde sensor and a unique catalytic filter detect and continuously destroy formaldehyde.¹ Powerful Air Multiplier™ technology then purifies, heats the whole room, and cools the user.²

The HEPA filter⁶ removes 99.97% of particles 0.3 microns⁷ in size, and the fully sealed design prevents pollutants from escaping. The three-phase purification process automatically senses, captures, and traps pollutants, effectively cleaning the air. The technology even detects and destroys formaldehyde.¹

The Air Multiplier technology generates the circulation power to draw distant pollutants into the machine, projecting purified air throughout the whole room.² Many household items, such as wood flooring, rugs, furniture, and fabrics, can release formaldehyde for years. Dyson's most advanced purification technology detects and destroys this harmful compound, converting it into water and CO2.¹

Users can choose between Fan mode for direct cooling with 0 to 350° oscillation and Backwards airflow mode to purify without cooling.⁴ This versatility allows the purifier to adapt to different user preferences and room conditions.

CAVEAT 1: ¹Third party full machine testing based on GB/T 18801-2018 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice. CAVEAT 2: ²Tested in maximum setting for air projection, tested in Auto mode for purification coverage, tested for room heating per relevant Dyson method DTM961. CAVEAT 4: ⁴Not applicable to heating. CAVEAT 6: ⁶Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. CAVEAT 7: ⁷Tested per ISO 29463.
