Wipe the amplifier loop, shrouds and other parts with a clean, dry cloth. Pay special attention to the oscillating channels on the front of the amplifying loop.

Do not use detergents or polishes to clean the machine.

Checking for blockages

We'd recommend checking for blockages in the following places:

The air inlet holes on the shrouds. The small aperture inside the amplifier loop. The air inlet holes behind the filters. The soft plastic mesh, which is visible inside the machine when the evaporator is removed.

Remove any dust or debris with a soft brush.

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.

Evaporator

The Dyson Purifier Humidify+Cool uses an evaporator to humidify the air. The room is humidified without the need for a cloud of mist. Instead, there will be an indication on the display when the machine is humidifying.

A water droplet animation on the display screen indicates that the machine is humidifying.

The water level in the tank will slowly decrease while your machine is humidifying.

The water will be depleted very slowly. Please allow a reasonable amount of time to pass before observing any change.

Auto humidify mode

While in Auto humidify mode, the onboard sensors will intelligently adjust the settings of the machine according to the temperature and humidity of your room.

Room humidity

Your machine will pause when the target room humidity has been reached, switching on again when the room humidity levels drop.

Airflow speed

The airflow speed will increase until the target humidity level has been reached.

Manual mode

Switch the machine to Manual mode.

Target humidity

In Manual mode, your machine will only humidify if the target humidity is higher than the ambient humidity.

Manually setting the humidity level

You can choose from 30%, 40%, 50%, 60% or 70%, using either the remote control or the Dyson Link app.

A water droplet animation on the display screen indicates that the machine is humidifying.

Increasing the airflow speed will help you to reach your target humidity.

Deep cleaning your machine

To always get the best performance from your Dyson purifying humidifying fan, it is important to carry out regular deep cleaning to remove any limescale.

Before and after long periods where humidification is not used, we recommend you run an additional Deep clean cycle.

In hard water areas, you may need to run the Deep clean cycle more frequently. We recommend you use filtered water to always get the best performance from your machine.

Please follow the steps in the video.

Manually setting the humidity level

You can choose from 30%, 40%, 50%, 60% or 70%, using either the remote control or the Dyson Link app.

Check your ambient humidity

The maximum setting on your machine is 70% humidity. If the ambient humidity of the room is 70% or higher, your machine will not humidify.

If the ambient humidity is lower than 70%, we recommend that you increase your target humidity to 70%. Your machine should start to humidify.

Purifying

Auto purify mode adjusts the airflow speed according to the air quality in the room. With Auto purify mode on, your machine will react to changes in the room's air quality.

Your machine will pause when the target air quality has been reached. It will resume when the air quality levels drop.

When your machine records a spike in PM2.5, PM10, VOC, or NO2, your machine will display the relevant pollutant icon.

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.

Severe/purple air quality

Severe/purple air quality denotes extremely low air quality with a high amount of pollutants.

Check the electrics

Check that the household electrics are on.

Check the plug and power cord for signs of damage.

Try the machine in a different plug socket.

Ensure the cable is firmly plugged into the back of the machine.

Wrong PSU warning
