We're glad the problem's been solved.

Please let us know if there's anything else we can help you with.

We need a little more information to help us solve your issue.

Please contact our Customer Support Team by calling 1-866-314-8881 or by clicking the Live Chat button in the bottom right corner of your screen. Dyson Supersonicᵀᴹ hair dryer Professional edition owners should call 1-866-861-2565.

Continuous monitoring

The continuous monitoring option is used for air quality, temperature and humidity data to be relayed to the machine and app at all times, even when you have turned the purifier off. The sensors have small fans that maintain airflow for continuous monitoring, but this should not cause any audible noise interference.

There may be instances when the display shows green, indicating high air quality, but the fan speed is still high. This is due to the machine constantly seeking to maintain a good air quality, and in scenarios such as rooms with leaky windows, the machine must work harder to maintain a good air quality.

This will only happen when the machine is set on auto. To turn off Auto mode, please select Manual mode, either using the remote control or on the app.

Please check the following on the app:

Swipe up to reveal the setting tab and tap to open options.

Swipe down to find the continuous monitoring option and tap to open.

Turn OFF the 'Collect data when in standby' option. (The icon will turn grey when turned off). Save the change by pressing 'Done' at the top right of the page.

Continuous monitoring can now also be turned on/off by pressing the 'Auto' button on the remote control for five seconds.

Night mode is not working

When in Night mode, your machine will automatically sense the ambient light level and adjust the resting screen brightness accordingly.

If the room is bright, (for example, the lights are on), the screen's display will be set to minimum brightness. If the room is dark (lights off) the screen is turned off.

In both scenarios, when the machine is interacted with, the screen brightness will uplift.

Has this resolved the problem?

The display will not stay on my selected screen

The interface is designed to stay on the screen you select. Please ensure the remote is not being accidentally pressed.

Has this resolved the problem?

My display is reading green but the fan is working at high speed

There may be times when the display is showing green but the fan speed is still high.

This is due to the machine always trying to maintain high air quality. For example, in a room with leaky windows, the machine has to work harder via a higher Fan speed to maintain a high air quality.

If you want the fan to be quieter, you can choose to change the airflow direction to face backwards, or turn the machine to manual mode and lower the airspeed.

Has this resolved the problem?

My readings are showing in different colours

The colour of the numbers and readings on the display are linked to the air quality of the respective category.

Green denotes a high air quality, with low pollutants, and red, low air quality with a high amount of pollutants.

Different categories can have different levels of pollutants at the same time, and will therefore display in different colours.

Has this resolved the problem?

The first time your purifier is turned on, the gas sensors will perform a self-calibration which takes one hour after which time they will work normally.

If the power cuts out within the hour, the initialisation period will continue from where it left off.

How long has your purifier been turned on for?

If your machine is new out the box and has not been turned on for over an hour, please allow a full hour to complete, with your purifier plugged into a secure power source.

Once the full hour has elapsed, turn the machine off and then on again, either with the main power button on the machine, or the remote control.

Has this resolved the performance issue?

Complete manual reset

If your purifier has been plugged into a stable power source for over one hour, and the VOC and/or NO2 screens still do not show, please unplug your machine from the wall, leave for one minute, plug back in, and then turn on using either the main power button, or the button on the remote.

Do the VOC and/or NO2 readings now show?

Important: Always unplug the machine before changing filters.

When the appliance detects that the non washable glass HEPA filters need replacing the display on the appliance will show an empty bar.

Unplug the appliance from the mains electricity supply. Slide the buttons down on either side of the shrouds.

The shrouds will release with the glass HEPA filters attached.

Empty the glass HEPA filters directly into the bin by pushing in both the purple tabs on the shrouds. Dispose of used filter units in accordance with local regulations.

Using the remote control

To operate, point the remote control toward the front of the base.

On/Off

Press the power ON/OFF button on the appliance or remote control to stop the purifier. The appliance will continue to monitor the air quality.

Airflow speed

Press the Airflow speed button to increase and decrease the airflow speed.

Oscillation On/Off

Press the Oscillation button to scroll through the options from 0 to 350.

Customise your oscillation settings in the Dyson Link app and it will appear as an option as you scroll through.

Information menu

Scroll through the options to monitor the performance of your appliance.

The menu will also allow you to access information about the pollutants in the air and the temperature and humidity levels.

When a particular type of pollutant causes air quality to decrease, the symbol for that pollutant will show in the display.

Auto mode

When Auto mode is selected the onboard sensors will intelligently adjust the settings of the appliance according to the quality of air.

The appliance will pause once the sensors detect that the target air quality level has been reached.

The sensors will continue to monitor the air quality, switching the appliance back on when air quality levels have dropped.

Customise your Auto mode and air quality settings in the Dyson Link app.

Airflow direction

Air will be purified continuously, whether the air is set to flow from the front or the back.

For purification and cool airflow, select the airflow direction to the front.

For purification without cool airflow from the front, select the airflow direction to the back.

Night mode

Night mode will dim the display and the appliance will run more quietly, making it ideal for use while sleeping. If Auto mode has been set, Night mode will reduce airflow speeds to range from 1 to 4. You can manually change the airflow from 1-10. Customise your Night mode settings in the Dyson Link app.

Auto mode

Auto mode adjusts the speed according to the air quality in the room.

When Auto mode is enabled (indicated by an A symbol in the bottom left corner of the display), the on-board sensors will intelligently adjust the speed of the purifier according to the air quality.

Increasing speed for poor air quality.

Reducing speed as the air quality improves.

If the air quality target is met, the air quality graph will show green. The air quality will continue to be monitored, with the fan running on a low speed in the background.

If the air quality worsens the air quality graph will show red and the purifier will automatically restart cleaning the room.

There may be times when the display shows green, but the fan speed is still high.

This is due to the machine constantly maintaining a high air quality.

If there is a factor in the environment such as leaky windows, the machine must work harder to sustain a high air quality.

Turning Auto mode on/off

Tap the remote icon on the bottom right corner of the home page.

Tap the power icon at the top of the menu and tap AUTO to select.

When Auto mode is enabled, 'Auto' is written at the top of the display.
