Dyson Purifier Hot+Cool Formaldehyde™ HP09 (Nickel/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 as small as 0.3 microns. A layer of activated carbon also removes odors and gases including VOCs.²
-
Destroys formaldehyde, continuously.⁺
The Dyson catalytic filter continuously traps and breaks down formaldehyde⁺ molecules 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.⁸
-
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.⁹ 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.

Frequently asked questions
Dyson engineers are perfectionists. Channeling our relentless dissatisfaction, we have re-engineered our latest purifiers to be fully sealed to HEPA H13 standard.⁹ Two phases of purification sit within a fully-sealed filtration and airflow system to trap pollutants inside, preventing them from leaking back into the air you breathe.
The Dyson Purifier Formaldehyde range has all of the capabilities found in our advanced purification products, but goes a step further to detect and destroy formaldehyde.⁺ An added solid-state sensor precisely detects formaldehyde, while our catalytic filter breaks it down into two safer molecules – carbon dioxide and water.
Formaldehyde is a polluting gas formed of carbon, hydrogen, and oxygen that is commonly found in homes. Sources of formaldehyde in your home could include paint and varnishes, air fresheners, mattresses, furniture, household cleaners, carpets, particleboard and plywood, electronics, dryer sheets, nail polish remover, moth balls, toys, fireplaces, and wood burning stoves.
HEPA grades refer to filter efficiency at a certain particle size. HEPA H13 is a filter with a 99.95% removal efficiency of particles down to 0.1 microns per liter of air. Dyson filters also capture 99.97% of particles down to 0.3 microns in size including common pollutants such as allergens, bacteria, viruses, pollen, and mold spores.
We recommend replacing the HEPA+Carbon filter roughly every 12 months, depending on how often you use it. That’s because over time filters can become clogged with pollutants and even let unpleasant odors back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen and via the myDyson app.⁵ The catalytic filter never needs replacing.
This machine is compliant with safety standard UL 1278, as required by the US government. For this reason, heating and temperature control are not available in the myDyson app.⁵ Please use your machine’s remote control instead.

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?
