Re-engineered to deliver 50% cleaner air*
Automatically senses, captures, and traps pollutants
Precisely detects and destroys formaldehyde1
Fully sealed to HEPA H13 standard.3
So what goes inside, stays inside.
Purifies, heats⁶ the whole room², and cools you
Dyson Purifier Hot+Cool Formaldehyde™ HP09 (White/Gold)
The valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Backward airflow mode and Fan mode.
Only Dyson purifiers have Air Multiplier™ technology to draw in distant pollutants and project purified air throughout the room.²
Dyson engineers designed the POLAR test to challenge the industry standard test methods - measuring purification, sensing, and circulation to ensure the whole room is purified properly.
In this 28.5m³ room, one fan mixes the air before the test, and another circulates air during the test. Only one sensor measures air quality.
In this 81m³ room, there are no fans except the air purifier with nine different sensors to measure even-room air quality.
Poor air quality isn't just a problem outside.
It's a problem inside too.
From pets and flowers, to sprays and stoves, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them.

Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO₂. And it self-regenerates, so it never needs replacing.¹
To prevent pollutants from leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier.³ So what goes inside, stays inside.
Smart purification, controlled by app or voice
Control and monitor air quality from anywhere with the Dyson Link app, or hands-free with compatible voice services.
Projects over 77 gallons of air a second for cooling airflow.
Air Multiplier™ technology projects purified, heated air throughout the room.² Once your target temperature is reached, heating automatically stops.
Airflow is diverted through the back of the machine, maintaining effective purification without cooling you.⁴
The catalytic filter never needs to be replaced. We recommend replacing the HEPA+Carbon filter when you're alerted by the Dyson Link app or every 12 months, whichever comes first.
For lighter sleepers, it monitors and purifies using the quietest settings along with a dimmed display.
Dyson engineers are perfectionists. Channeling our relentless dissatisfaction, we have re-engineered our latest purifiers to be fully sealed to HEPA H13 standard.³ 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.¹ 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 Dyson Link 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 Dyson Link app. Please use your machine’s remote control instead.
