Understanding the icons on your LCD screen
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 oxidizing 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 colored 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 colored bar is highlighted, your machine is detecting a very low level of the type of pollutant.
When the yellow section of the colored bar is highlighted, your machine is detecting a moderate level of the type of pollutant.
When the orange section of the colored bar is highlighted, your machine is detecting a high level of the type of pollutant.
When the red section of the colored 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 customize the angle, speed and direction of airflow.
Set a timer to turn your machine off for any time between 15 minutes and 9 hours, using your remote control.
Maintaining your machine
How to replace your Dyson purifier fan filter
Monitoring your Dyson filter's life is easy. Watch how you can get this information on your Dyson Pure Hot+ Cool to know when to replace your filter and how to replace it.
Cleaner indoor air, day after day
Over time, purifier filters can get clogged up with microscopic pollutants, and even let unpleasant odours back into the room. That's why we recommend changing your filter when your machine alerts you - so it keeps on running effectively, for a cleaner environment.
