Key features
-
Diffused mode to purify without cooling youDiverts airflow through the back of the machine. To purify the room, without feeling the airflow or cooling you.
-
Quiet, even at full powerAcoustically engineered to reduce turbulence, so it’s 20% quieter than the previous model. Perfect for night, or a peaceful working environment.
-
Smart technologyThe MyDyson™ app lets you see which pollutants have been captured, set schedules and more. Control hands-free, using compatible voice services such as Amazon Alexa, Google Assistant or Siri.6
-
Easy maintenanceChanging the filter is quick and easy. The machine’s LCD screen and MyDyson™ app6 notifies you when it needs to be replaced.

Discover the pioneering technology inside
Senses and reports, automatically
Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality.
Advanced three-stage filtration with HEPA H13
Captures gases4, odours, dust, allergens, bacteria and 99.95% of particles as small as 0.1 microns.5 Continuously destroys formaldehyde.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. So what goes inside, stays inside.7
Destroys formaldehyde in billions of catalytic tunnels
Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO2.2 And it self-regenerates, so it never needs replacing.
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.7 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.2 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 litre of air. This includes common pollutants such as allergens, bacteria, viruses, pollen, and mould 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.
The Dyson Purifier Cool De-NOx is both an air purifier and a powerful cooling fan. The machine uses Dyson Air Multiplier™ technology to project a powerful stream of high-velocity, purified air to cool you down quickly.
