Unscrew the remote control's battery compartment.

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

Check and clean machine

Unplug your machine from the mains power outlet.

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.

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.

Trickling or gurgling noise

Should the drip tray overfill, the machine's water return float is activated. As the water returns to the tank, a trickling or gurgling noise may be heard. The display screen will prompt that a deep clean cycle is to be run.

For a step by step guide on running a deep clean please continue to the next step.

A trickling or gurgling noise can be heard if the evaporator is missing. In this instance, please replace the evaporator in the machine.

If the evaporator is missing, to order a replacement, please select 'Evaporator' from the available options.

Display screen

The humidification dial on your LCD screen shows the current room humidity in grey, and the target humidity in blue.

When your machine is humidifying, the dial will appear blue. A grey dial indicates that the humidifier is inactive.

Increasing the airflow speed

First, check the current humidity level in the room.

Press the information button on the remote control until you reach the relative humidity information screen.

If the ambient humidity level is higher or lower than the target humidity, increasing the airflow speed should help you reach your target.

Your machine is engineered to purify and humidify single rooms, so you should use it where you spend the majority of your time at home.

When placing the machine, allow for a few feet of clearance on all sides so that the air can circulate effectively. Place it away from radiators, draughts or air vents. Turn off any air conditioning and keep doors and windows closed during use.

If the machine is being used in a large open space with windows and doors open, it may take longer to reach the humidity level.

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.

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.

Point the remote directly at the front of the machine while pressing the button.

Using the remote option in the app, check if the oscillation changes.

Changing 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.

Ensure the correct button on remote is being pressed.

Toggle through the oscillation setting using the oscillation button on the remote until 0° is displayed.
