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.

  • The LCD screen's icons showing different levels of pollutants

    Good

    When the green section of the coloured bar is highlighted, your machine is detecting a very low level of the type of pollutant.

  • The LCD screen's icons showing different levels of pollutants

    Fair

    When the yellow section of the coloured bar is highlighted, your machine is detecting a moderate level of the type of pollutant.

  • The LCD screen's icons showing different levels of pollutants

    Poor

    When the orange section of the coloured bar is highlighted, your machine is detecting a high level of the type of pollutant.

  • The LCD screen's icons showing different levels of pollutants

    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.

  • Auto mode

    In Auto mode, your machine monitors and responds to air pollution. When it detects pollutants, it automatically projects purified air.

  • Oscillation angle

    You can set the oscillation angle of your purifying fan, from 45° to 350°.

  • Airflow speed

    Choose from 10 different fan speed settings, and switch between front projection and Diffused modes.

Maintaining your machine

You can find out how to monitor and replace the combination filter in our video guide. Your Dyson Cryptomic™ filter is permanent, so you don’t need to change it.

Frequently asked questions

The combination filter needs to be changed after 12 months, based on 12 hours’ use a day. The Dyson Cryptomic™ filter is permanent, so you don’t need to change it.

If you're concerned by the brightness of your purifying fan heater's LCD display, consider enabling Night-time mode using your remote control or the Dyson Link app. During operation, a small moon icon indicates that your purifier is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.

If auto mode is enabled, AUTO will be illuminated on your purifying fan's LCD display. When your machine is purifying the air, AUTO will be in white. When the air in the room is purified, it will turn green and your purifying fan will remain idle until pollutant levels rise.

Your purifying fan's auto mode is designed to manage the air quality in your home without you having to operate the machine – so it's only on when it needs to be. If you or someone in your home suffer from allergies or respiratory illnesses, we particularly recommend using your machine's auto mode.

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

Your purifying fan heater works most efficiently in a sealed environment – opening the windows can allow more pollutants to enter the air in your home, which means your machine will take longer to work.

Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifier fan's speed settings as the temperature changes. For personal cooling in summer, use settings 4-10. In colder periods, enable diffused mode. It projects air through the back of the machine, to avoid unwanted cooling.
