Connecting your machine
The Dyson Link app allows you to control your purifier fan heater, direct from your device.¹ Follow three simple steps to connect the app to your machine.
Download the Dyson Link app.
Hold your device next to your machine's display. This will allow your machine to detect your mobile device.
Press the power button on your machine to activate the pairing process. Then follow the on-screen instructions to complete connection set-up.
Understanding your LCD screen's icons
The icons on the built-in LCD screen show you 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.
Volatile Organic Compounds (VOCs)
Shows gases released from a wide range of sources, such as aerosol sprays and air fresheners. They include formaldehyde and 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 both the HEPA and active carbon filters. So you know which one to replace and when.
Understanding pollutant levels
When a pollutant causes the air quality to drop, the relevant icon will appear on the LCD screen. The coloured bar on the left of the screen will indicate how much of the pollutant is present, and will continually update as your machine purifies the air.
When the green section of the coloured bar is highlighted, your machine is detecting a very low level of the type of pollutant.
When the yellow section of the coloured bar is highlighted, your machine is detecting a moderate level of the type of pollutant.
When the orange section of the coloured bar is highlighted, your machine is detecting a high level of the type of pollutant.
When the red section of the coloured bar is highlighted, your machine is detecting a very high level of the type of pollutant.
Oscillation and airflow
Watch our video guide on how to customise the angle, speed and direction of airflow.
Set when you want your machine to be on and off, up to seven days in advance, with the Dyson Link app.
For the quietest settings and a dimmed screen, set your machine to Night-time mode using your remote control.
Set a timer to turn your machine off for any time between 15 minutes and 9 hours, using your remote control.
Voice control. All you have to do is ask.
