Re-engineered to deliver 50% cleaner air*
Dyson's most advanced filtration system combines a precise, solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde.¹ An activated carbon filter removes gases and odors and a HEPA filter captures 99.97% of particles 0.3 microns in size. And Dyson purifiers have powerful Air Multiplier™ technology to purify and heat the whole room.²
Dyson Purifier Hot+Cool Formaldehyde™ HP09 (White/Gold)
Technology
-
Senses and reports, automatically
Integrated sensors constantly analyze your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.
-
Captures gases and ultrafine particles
The HEPA filter captures 99.97% of particles 0.3 microns in size. A layer of activated carbon also removes odors and gases including VOCs.
-
Destroys formaldehyde, continuously
The Dyson catalytic filter continuously traps and breaks down formaldehyde molecules¹ into water and CO₂. And it never needs replacing.
-
Purifies the whole room
Only Dyson purifiers have Air Multiplier™ technology. It generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.²
-
Fully sealed to HEPA H13
In our latest purifiers, it's not just the filter that meets HEPA H13 standard, it's the whole machine.³ So what goes inside, stays inside.
-
Precisely detects formaldehyde
Our latest purifiers use a solid-state sensor to detect formaldehyde molecules 500 times smaller than 0.3 microns and maintains precision for the lifetime of the machine.
Features
-
Heats when needed⁶
With long-range projection, it’s quick to heat the whole room evenly.²
-
Cools you when needed
A powerful stream of purified airflow can cool you down when desired.
-
Backward airflow mode
Diverts airflow through the back of the machine. To purify, without cooling you.⁴
-
App control
Control and monitor your air quality from anywhere using the MyDyson app⁵. Heating cannot be controlled via the MyDyson app due to safety standard UL 1278, as required by the US government. Please use remote to control heating.

Cleaner air, cleaner home: how to maintain a healthier space during home renovations
Moving and home makeovers involve new furniture and paint, which could add to the levels of a potentially harmful pollutant called formaldehyde in the home. Here's how to maintain a healthier space during moves and renovations.

Formaldehyde: the invisible indoor pollutant
Although the smell of new paint might fade over time, the emission of potentially harmful gases, such as formaldehyde, can persist. Pollutants like these can continuously ‘off-gas’ for a number of years – but what exactly is formaldehyde and why is it in our homes?
