Air that reaches all the way
The cone-shaped outlets gather the airflow and project it far into the room, while new air is drawn in through the filter below.
Everything in the app
The MyDyson app shows what the sensors read, what has been captured and lets you set schedules wherever you are.
Auto mode does the rest
When the sensors detect pollutants it raises the fan speed; when the air is clean it slows down again and saves power.

★★★★★4.3 out of 5 · 155 ratings on Dyson
★★★★★Top
Top features for a 100 m² flat. Controlling it with the Dyson app is really simple and intuitive.

★★★★★Fantastic features
What a fantastic piece of equipment. The filtration system works well and the airflow is lovely. There is hardly any noise. When used correctly, especially on auto mode, picks up any smells. Fully recommend.

★★★★★Dyson Purifier Blue/Gold
Sometimes having 2 dogs meant the house was beginning to smell but this unit is amazing and eliminates all odour

★★★★★Massive and effective
Massive and powerful. It's effective in a 40 m² room. I also have smaller Dyson purifiers that weren't enough. It's a good product.

★★★★★Very effective
We are very satisfied with our purchase, the purifier is effective and quiet. Very good quality and easy to use, and the wheels for moving it work very well, even on our uneven tiled floor. The settings via the phone or the remote are easy.

Description
An air purifier for large rooms and open-plan spaces, built to be quiet. Cone-shaped outlets project the purified air far into the room – over 80 litres per second according to Dyson – while drawing air in through the sealed filter.
You set the airflow at 0°, 25° or 50°, or choose Breeze mode, which varies like a gentle breeze. Sensors read particles, gases, formaldehyde and CO₂, and in Auto mode it adapts by itself and only uses power when needed. It also warns you when the CO₂ level in the room gets high, so you know it's time to air the room.
Everything shows on the display and in the MyDyson app, where you also set schedules. Hidden wheels let it roll easily on hard floors, and the filter changes with one click.
