Using your purifier

Understanding the LCD screen icons
The icons on your LCD screen show which pollutants are present, reporting them in real time. They also tell you about temperature, humidity and filter life.
Indoor Air Quality Index (AQI)
Shows your air quality over the last 12 seconds, or over the last 24 hours.
Particulate matter PM2.5
Shows microscopic particles smaller than 2.5 microns, including smoke, bacteria and allergens.
Particulate matter PM10
Shows particles smaller than 10 microns, including pollen, dust and pet dander.
Shows particles of formaldehyde, a volatile gas that can emit for years from household flooring and furniture.
Volatile Organic Compounds (VOCs)
Shows gases released from a wide range of sources, such as aerosol sprays and air fresheners. They include benzene, household fumes and odours.
Nitrogen Dioxide (NO2)
Shows oxidising gases such as NO2, released by combustion. Includes cigarette smoke, car emissions, candles and gas stoves.
Shows how much filter life remains on the HEPA+Carbon filter. So you know when to replace it.
Understanding pollutant levels
When a pollutant reduces your air quality, its icon appears on screen. In this case, PM10. The coloured bar on the left indicates how much of the pollutant is present, and will continually update as the machine purifies your air.
When the yellow section of the coloured bar is highlighted, your purifier is detecting a moderate level of the type of pollutant.
When the green section of the coloured bar is highlighted, your purifier is detecting a very low level of the type of pollutant.
When the orange section of the coloured bar is highlighted, your purifier is detecting a high level of the type of pollutant.
When the red section of the coloured bar is highlighted, your purifier is detecting a very high level of the type of pollutant.
Using the remote control
Activate Auto mode
Select Auto mode and your on-board sensors will intelligently adjust settings according to your air quality.
Setting the oscillation angle
Watch our video guide on how to customise the angle of oscillation for your machine. Choose from a range between 45° up to 350°.
Adjusting the airflow
Both the speed and direction of airflow can be adjusted. For powerful, personal cooling from the front, or diffused air diverted through the back of the machine.
Sleep timer and Night mode
Set the Sleep timer to turn your purifier off, or use Night mode for the quietest settings and a dimmed screen.
Maintaining your purifier
To ensure optimum air purification performance, we recommend replacing your HEPA+Carbon filter every 12 months. Your Catalytic filter never needs replacing.
Works with smart voice control
Control your Dyson purifier with your voice.2
Just say “Hey Google” and you can use Google Assistant to control all your connected purifiers. Or set a routine to automate how your machine works with other devices in your home.
Some things you can say:
When you've connected your Dyson purifier to your
voice assistant, you could try saying:
"Alexa, turn on my Dyson machine"
"Hey Google, turn up the temperature"
"Hey Siri, enable Auto mode"
