Removing the battery

Unscrew the remote control's battery compartment.

Loosen the base and pull it away from the remote. Replace the battery with type CR 2032.

When your purifier switches from front to rear airflow there may be a clicking sound as the motor adjusts direction.

This is a normal sound for the purifier to make and is not an indicator of anything wrong with your machine.

Check base

Check around the base of the machine for any debris or obstructions.

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.

Retest the machine.

Restart the machine

Unplug the machine and leave it for 10 seconds.

Plug the machine back in and retest.

Remove the filters

Switch off and unplug your machine.

To remove your HEPA+Carbon filter, push down on the buttons either side of your machine to release the outer cover. Push down on the tabs to remove the filter.

With the HEPA+Carbon filter removed, put the outer covers into position on your machine and push firmly until they both click securely into position.

Plug in and switch your machine.

Ensure correct button on remote is being pressed to adjust the airflow.

Clean the machine

To always get the best performance from your Dyson purifying fan, it’s important to regularly clean it and check for blockages.

If your machine is dusty, wipe with a damp lint-free cloth.

Look for blockages in the air inlet holes on the filter and the small aperture inside the loop amplifier.

Use a soft brush to remove dust and debris.

Don’t use detergents or polishes to clean your machine.

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.

If your machine is new out of the box and has been turned on for less than one hour, the machine may still be calibrating. This process takes up to one hour to complete. Please leave the machine running during this time.

After one hour, turn the machine off and then on again. Press the power button on either the main body or the remote control.

Factory reset

If your purifier has been plugged into a stable power source for over one hour and the selected readings still do not show, we advise that you perform a factory reset.

Press and hold the power button on both the main body and the remote control.

Continue to hold the buttons until the LCD screen shows a countdown timer.

Once the countdown has been completed, the machine will have reset.

Your purifier will turn on automatically. Leave your machine running for one hour to perform self-calibration.

Note: By resetting the machine, your Wi-Fi network details will have been removed and your purifier will no longer be connected to the Dyson Link app. You will need to restart the connection journey.

Restart the machine

Switch off and unplug the machine.

Ensure all outside doors and windows are closed.

Vacuum the four sensor slots to the left of the LCD screen.

Plug in and test the machine.

Switch off and unplug the machine.

Move the machine to another room.

Plug in and test the machine.

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.

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.

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.

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.
