LCD screen icon advising to increase airflow

Achieving your manual humidity setting

If your machine’s LCD shows this icon, 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.

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

  • Humidification dial

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

  • Filter life

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

  • Evaporator status

    Indicates the evaporator's level of mineral build-up, and how soon a Deep clean cycle is required.

  • Maintenance alerts

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

  • 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

Frequently asked questions

How often does the filter need to be changed?

The Combi filter needs to be changed after 12 months, based on 12 hours’ use a day.

How long can my machine humidify for?

With a full tank, your machine can humidify continuously for up to 36 hours in fan mode 1.

Can I switch off humidification?

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

How often should I run a Deep clean cycle?

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.

Will the humidifier overheat if it runs out of water?

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

Can multiple users share the same machine?

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.

Where should I place my machine?

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.
