Achieving your manual humidity setting

If your machine’s LCD shows the icon opposite, you're being advised to manually increase the airflow to eight or above. This may help you to reach your desired humidity level faster.

Other steps that can help include:

  • Moving your machine away from air vents
  • Keeping your machine away from high traffic doorways
  • Using a lower setting for heating or air conditioning units.
  • Understanding your screen's icons

    The icons on the LCD screen show you which pollutants are present, reporting them in real time. They also tell you about humidity and filter life, and will alert you when it's time to run a Deep clean cycle.

    • Indoor Air Quality Index (AQI)


      Shows your air quality over the last 12 seconds, or over the last 24 hours.

    • Particulate matter PM2.5


      Your machine is sensing microscopic particles smaller than 2.5 microns, including smoke, bacteria and allergens.

    • Particulate matter PM10


      Your machine is sensing particles smaller than 10 microns, including pollen, dust and pet dander.

    • Volatile Organic Compounds (VOCs)


      Your machine is detecting gases released from a wide range of sources, such as aerosol sprays and air fresheners.

    • Nitrogen Dioxide (NO2)


      Your machine is detecting oxidising gases such as NO2, released by combustion. Includes cigarette smoke, candles and car emissions.

    • Humidifying to 50% target


      Shows your machine is humidifying to reach the set 50% target.

    • Humidifying to Auto target


      Shows your machine is adjusting its settings according to the temperature and humidity of your room.

    • Humidification target met


      Shows your humidification target has been met.

    • Humidification target lower than room humidity


      Shows your target humidity is less than the current room humidity.

    • Filter life


      Shows how much filter life remains on your Combi filter. So you know when to replace it.

    • Evaporator status


      Indicates how full the evaporator is with limescale, and how soon a Deep clean cycle is required.

    • Maintenance alerts


      Shows a live diagnosis, so you know what to do.

    • Humidification dial


      Shows the current room humidity in grey, and the target humidity level in blue.

    • Indoor temperature


      Shows the room's temperature.

    • Relative humidity info screen


      Shows the current humidity level in your room.

    • Wi-Fi


      Shows the current status of connection to the Wi-Fi network.

    • Increase your airflow


      If you see this screen, increase the airflow to eight or above. This may help you to reach your desired humidity level faster.

    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.

    • 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.

    • Extremely poor


      When the dark red section of the coloured bar is highlighted, your machine is detecting an extremely high level of the type of pollutant.

    • Severe


      When the purple section of the coloured bar is highlighted, your machine is detecting a severe 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.

    • It's quick and easy to run a Deep clean cycle


      You can run a Deep clean cycle in nine simple steps. After pressing the Deep clean cycle button on the front of your machine, start by following steps one and two.

    • Remove the filter covers and water tank


      Push down on the release buttons to remove the filter covers. The inner door will spring open. Push down the water tank release buttons. Slide the water tank out of your machine and unclip the cap.

    • Remove the evaporator


      Remove the evaporator from your machine, place it in the water tank and refit the cap.

    After completing steps one and two, take the water tank to the sink and follow steps three to nine – as shown on your water tank's sticker.

    • Prepare the cleaning solution


      Remove the cap and evaporator. Fill the water tank halfway to the Max level with cold tap water. Add 150g of citric acid and shake gently until all the citric acid has dissolved. Place the evaporator back in the tank and fill to the Max level with cold water.

    • Replace cap and secure clips


      Make sure you wipe off any excess water to avoid drips.

    • Start the Deep clean cycle


      Slide the water tank into your machine. When prompted by the LCD screen, press the Deep clean cycle button. The Deep clean cycle will start and a countdown timer will appear.

    • Remove the water tank


      When the LCD screen shows the Deep clean cycle is complete, push down the water tank release buttons. Slide the water tank out of the machine and carry to the sink.

    • Rinse the evaporator and water tank


      Unclip the cap, take the evaporator out of the water tank and rinse under a cold tap. Wipe away any excess water. Rinse the water tank under a cold tap. Wipe the inside of the water tank to remove any excess solution and any debris.

    • Fill the water tank with cold water


      Refill the tank to the Max level, wipe off any excess water and replace the cap.

    • Reinsert the evaporator and water tank


      Push the evaporator back into your machine, close the inner door and replace the filter covers. Slide the water tank back into your machine.

    Keep the cap dry

    Keep the cap on the water tank dry when you run a Deep clean cycle or fill the tank. It contains power connections and should not be washed. If wet, wipe thoroughly with a dry cloth. Make sure the cap and connections are completely dry before refitting.

    How to change your machine's filter

    You can find out how to monitor and replace your Combi filter in our video guide.

    Yes. The machine works as a purifier humidifier, or just a purifier fan.

    This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas. You can select your water hardness with the Dyson Link app1.

    No. It has a sensor to detect if it’s out of water. The screen alerts you to refill your water tank when needed.

    Yes, an unlimited number of users can use a single machine. The machine will only ever choose the most recent update. For example, if more than one person was updating the scheduling, the most recent change will be the one the machine progresses with.

    Your machine is engineered to purify and humidify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there's at least a few feet of clearance on all sides, so that the air can circulate effectively.
