Key Features:
Quiet, even at full power
An acoustically engineered motor bucket records just 56dBA of sound power at full-speed. With no compromise on performance.
Control your air quality wherever you are
The MyDyson™ app gives you autonomy over your air quality. View which particles have been captured, set schedules, browse reports, and more.5
Auto mode
With the Auto mode feature, your purifier can sense, capture and report on pollutants in your home in real-time. This saves energy – meaning it only purifies when needed.6
Smart home purification
Connect and then control your air quality, hands-free, with compatible smart home voice services.7
Whole-machine sealed to HEPA H13 grade8
Three phases of purification sit within our fully-sealed machine to trap pollutants inside, removing them from the air you breathe. Giving you reassurance that what goes inside, stays inside.
1 The ability of purifying a large room up to 100m2 (10m*10m) proven from a Computational Fluid Dynamics (CFD) modelling, with the purifier placed in a corner of the room running at the maximum flow and horizontal projection reaching 10 metres to fully mix the room. The projection distance was measured from internal flow reach testing under the maximum directional airflow. The actual performance in real life condition may vary.
2 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29364).
3 Tested to JEM 1467 (acetic acid, acetaldehyde, ammonia), GB/T18801 (formaldehyde, benzene) and DTM-003282 (NO2). Gas capture rates vary.
4 Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
5 App functionality may vary per market. Requires Wi-Fi and app enabled device. Standard data and messaging rates may apply. Requires iOS version 10 or above, or Android version 5 or above. Your mobile device must have Bluetooth 4.0 support.
6 In Auto mode.
7 Refer to the MyDyson app for compatible smart home devices and voice services.
8 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.

Why Buy?
Breathe Easy in Every Corner of Your Home
If you want genuinely clean air throughout your entire home — not just in one corner — this Dyson purifier is built to deliver exactly that, quietly and consistently.
It covers spaces up to 100 square metres, so it's powerful enough to work across open-plan living areas, large bedrooms, or connected rooms without breaking a sweat. It captures 99.95% of airborne viruses and bacteria, and it's specifically designed to tackle formaldehyde — a harmful gas that can off-gas from furniture, flooring, and paint for years without you knowing. The airflow can be angled three ways, so you can direct purified air exactly where it's needed most, whether that's across a room or straight up to circulate gently.
Despite its serious performance, it runs quietly enough to sit in a bedroom or living room without becoming a distraction. The remote control means you don't have to get up to adjust settings, and the Bright Nickel and Prussian Blue finish looks sharp enough to sit out in the open rather than being tucked away.
Buy This If…
- You have a large open-plan home and want whole-space air coverage
- You're concerned about hidden pollutants like formaldehyde from new furniture or flooring
- Someone in your household has allergies, asthma, or respiratory sensitivities
- You want a purifier that runs quietly in the background without disrupting sleep or conversation
- You want something that looks good enough to leave out as part of your décor
