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.
-
Good
When the green section of the coloured bar is highlighted, your machine is detecting a very low level of the type of pollutant.
-
Fair
When the yellow section of the coloured bar is highlighted, your machine is detecting a moderate level of the type of pollutant.
-
Poor
When the orange section of the coloured bar is highlighted, your machine is detecting a high level of the type of pollutant.
-
Very poor
When the red section of the coloured bar is highlighted, your machine is detecting a very high level of the type of pollutant.
-

Maintaining your machine
Running a Deep clean cycle
The monthly Deep clean cycle eliminates bacteria and limescale throughout your machine's water system. Your machine's LCD screen and the Dyson Link app will let you know when it's time. You'll need 150g of citric acid, then just follow the steps in our video guide.
We recommend only using citric acid when running a Deep clean cycle. It's a safe, natural cleaning agent, and is widely available.
