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?
Clean, quiet air across your whole living space
The Dyson Purifier Big+Quiet Formaldehyde is built for larger or open-plan homes, purifying rooms up to 100 square metres while running at just 56 decibels on full power. If you have been looking for a Dyson air purifier that covers real living space without adding noise to the room, this is the one to consider.
Three stages of filtration pull in allergens, dust, pet dander and household odours, while a fully sealed system stops anything captured from leaking back into the air. It also detects and permanently breaks down formaldehyde, a gas that can seep from new furniture, flooring and cabinetry for years after installation. Auto mode reads the air in real time and only ramps up when it needs to, so you get clean air without the machine working harder than necessary.
Running on just 50W, it sits comfortably in a lounge, bedroom or kitchen without pushing up power bills. The bright nickel and Prussian blue finish suits modern interiors, and the MyDyson app lets you check air quality, set schedules and adjust settings from your phone, so the purifier fits quietly into daily life rather than demanding attention.
Buy this if…
- You want a Dyson purifier big+quiet enough for bedrooms and shared living areas
- Your household has allergies, asthma or general sensitivity to dust and pollen
- You have recently renovated or bought new furniture and want formaldehyde removed
- You need one purifier to cover a large or open-plan room
- You like checking and controlling air quality through an app rather than buttons
