Dyson Purifier Hot+Cool Formaldehyde HP09

Dyson's latest purifiers combine intelligent sensing with an advanced filtration system. Three phases of purification are housed within a fully sealed filtration and airflow system, ensuring that what goes in, stays in. A solid-state formaldehyde sensor and a unique catalytic filter work together to detect and continuously destroy formaldehyde.¹ The powerful Air Multiplier™ technology then purifies, heats the entire room, and cools the user.²

The HEPA filter¹ removes 99.97% of particles 0.3 microns⁷ in size, and the purifier is fully sealed, ensuring that pollutants are captured and trapped within the machine. The three phases of purification work seamlessly within the sealed filtration and airflow system.

The purifiers automatically sense, capture, and trap pollutants, providing cleaner air. They even detect and destroy formaldehyde,¹ a common household pollutant that can be released from various materials for years.

Dyson's advanced purification technology utilizes Air Multiplier technology to generate the circulation power needed to draw distant pollutants into the machine, projecting the purified air throughout the entire room.² Users can choose between Fan mode for direct cooling with adjustable oscillation, and Backwards airflow mode to purify without cooling.⁴

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.
