When the appliance detects that the nonwashable glass HEPA filters need replacing the display on the appliance will show a full 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.

Push the new glass HEPA filters into the shrouds until secure. Push the shrouds until they click back into position in the base.

Press and hold the Night mode button on the remote control. The display on the appliance will countdown from five, finishing with the default screen. The glass HEPA filter level will be reset and the appliance is ready to use.

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.

Please try taking the filters off, then reattaching them to ensure they are correctly clicked into place. When attaching the filters, press in and up, and check there are no gaps or loose areas.

If the filters are not attached correctly, a triangle warning may show on your screen. If this happens, please reattach the filters securely.

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.

Ensure the power cord is plugged into the centre of the base.

Plug the machine back in and retest.

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.

Plug the machine back in and retest.

When not in use, unplug from the mains electricity supply.

To remove the carbon filters: press the tabs on both sides of the filters.

Plug the machine back in and retest.

Please ensure you have the most up to date software downloaded before beginning any checks. We strongly recommended enabling auto-updates in your Dyson Link app settings, to allow the most up to date software to be installed as soon as it is available.

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.

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

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.

Fault

Reset the machine.

Unplug the machine and leave it for 10 seconds.

Plug the machine back in and retest.

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.

If your screen is not displaying correctly (incorrect reading, white screen etc), please ensure you have updated all the software to the latest version.

When setting up a product, we strongly recommend enabling auto-updates, to allow your machine to easily download the latest software.

To enable auto-updates, open the Dyson Link app and click the cog at the top right of the home screen.

Click 'Your Purifier's settings'.

Scroll down to 'Software' and enable Auto-update.

Restart the machine

Plug in and test the machine.

Switch off and unplug the machine.

Move the machine to another room.

Plug in and test the 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 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.

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.
