Outdoor air readings

Hello @GHann5,

Thank you for posting a question.

We acquire outdoor air quality and weather data from 3rd parties, which enables us to provide all of our Dyson Link App users with a common standard on Air Quality (AQ). We regularly review our data sources to check we’re serving the most accurate data available to users at any given time.

To read more about outdoor Air Quality (AQ) in the App, when on the home screen of your registered Air Treatment machine, scroll up and click on the ‘AQI’ result. This will take you through to an overview screen which explains the ‘Air Quality scale’. By scrolling to the bottom of this screen and selecting ‘Learn more about air quality’ you will be taken to the local government site where you can then read about the ‘Air Quality Index’ in more detail.

I hope this helps to answer your question.

Thanks,

Kelly
