Understanding your LCD screen icons
The icons on the built-in-LCD screen show you which pollutants are present, reporting them in real time. They also tell you about humidity and filter life, and will alert you when it's time to run a Deep clean cycle.
Indoor Air Quality Index (AQI)
Shows your air quality over the last 12 seconds, or over the last 24 hours.
Displays particles of formaldehyde, a volatile gas that can emit for years from household flooring and furniture.
Particulate matter PM2.5
Your machine is sensing microscopic particles smaller than 2.5 microns, including smoke, bacteria and allergens.
Particulate matter PM10
Your machine is sensing particles smaller than 10 microns, including pollen, dust and pet dander.
Volatile Organic Compounds (VOCs)
Your machine is detecting gases released from a wide range of sources, such as aerosol sprays and air fresheners.
Nitrogen Dioxide (NO₂)
Your machine is detecting oxidising gases such as NO₂ released by combustion. Includes cigarette smoke, candles and car emissions.
Shows the room's temperature.
Relative humidity info screen
Shows the current humidity level in your room.
Shows the current room humidity in grey, and the target humidity level in blue.
Humidifying to 50% target
Shows your machine is humidifying to reach the set 50% target.
Humidifying to Auto target
Shows your machine is humidifying to reach the Auto target.
Humidification target met
Shows your humidification target has been met.
Humidification target lower than room humidity
Shows your target humidity is less than the current room humidity.
Shows how much filter life remains on your combination filter, so you know when to replace it.
Indicates how soon a Deep clean cycle is required.
Shows it's time to refill the water tank.
Shows the current status of connection to the Wi-Fi network.
Understanding pollutant levels
When a pollutant causes the air quality to drop, the relevant icon will appear on the LCD screen. The coloured bar on the left of the screen will indicate how much of the pollutant is present, and will continually update as your machine purifies the air.
When the green section of the coloured bar is highlighted, your machine is detecting a very low level of the type of pollutant.
When the yellow section of the coloured bar is highlighted, your machine is detecting a moderate level of the type of pollutant.
When the orange section of the coloured bar is highlighted, your machine is detecting a high level of the type of pollutant.
When the red section of the coloured bar is highlighted, your machine is detecting a very high level of the type of pollutant.
When the dark red section of the coloured bar is highlighted, your machine is detecting an extremely high level of the type of pollutant.
When the purple section of the coloured bar is highlighted, your machine is detecting a severe level of the type of pollutant.
Maintaining your machine
How to run a Deep clean cycle
The monthly Deep clean cycle removes mineral build up from your machine's water system. Your machine's LCD screen and the Dyson Link app will let you know when it's time. You'll need 150g of citric acid, then follow the steps in our video guide or user manual.
We recommend only using citric acid when running a Deep clean cycle. It's a safe, natural cleaning agent, and is widely available.
The cap on the water tank contains power connections. When you fill the tank or run a Deep clean cycle, make sure the cap is completely dry before refitting.
It's quick and easy to run a Deep clean cycle
You can run a Deep clean cycle in nine simple steps. After pressing the Deep clean cycle button on the front of your machine, start by following steps one and two.
Remove the covers and water tank
Push the shroud release buttons to remove the shrouds. The inner door will spring open. Push the water tank release buttons, slide the tank out of your machine, and unclip the cap.
Remove the evaporator
Remove the evaporator from your machine, place it in the water tank and refit the cap.
Follow steps three to nine- as shown on your water tanks sticker.
Prepare the cleaning solution
Remove the cap and evaporator. Fill the water tank half-full with cold tap water. Add 150g of citric acid and agitate until dissolved. Place the evaporator back in the tank and fill to the Max level with cold water.
Secure clips and wipe excess water
The cap contains power connections, so must be kept dry. If wet, wipe thoroughly with a dry cloth, and make sure the cap and connections are completely dry. Replace the cap and secure the cap clips.
Start the Deep clean cycle
Slide the water tank into your machine. When prompted by the LCD screen, press the Deep clean cycle button. The cycle starts and a countdown appears.
Remove the water tank
When the LCD screen shows the Deep clean cycle is complete, push down the water tank release buttons. Slide the water tank out of the machine and carry to the sink.
Rinse the evaporator and water tank
Unclip the cap, remove the evaporator and rinse under a cold tap. Wipe away excess water. Rinse the water tank under a cold tap. Wipe the inside of the tank to remove any excess solution or debris.
Fill the water tank with cold water
Refill the tank to the Max level, wipe off any excess water and replace the cap.
Reinsert the evaporator and water tank
Make sure the cap and connections are completely dry. Push the evaporator back into your machine, close the inner door and replace the filter covers. Slide the water tank back into your machine.

Frequently asked questions
The most comfortable humidity level varies depending on the temperature.² In Auto mode, your machine constantly monitors air quality, automatically adjusting airflow to reach and maintain the most comfortable humidity level.
The combination filter needs to be changed every 12 months, based on 12 hours’ use a day.
With a full tank, your machine can humidify continuously for up to 36 hours in fan mode.³
Yes. The machine works as a purifier humidifier fan, or just a purifier fan.
This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas. You can select your water hardness with the Dyson Link app.¹
No. It has a sensor to detect if it’s out of water. The screen alerts you to refill your water tank when needed.
Yes, an unlimited number of app users can control a single machine. The machine will only ever choose the most recent update. For example, if more than one person was updating the scheduling, the most recent change will be the one the machine progresses with.
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, make sure there's at least a few feet of clearance on all sides, so that the air can circulate effectively. Place away from radiators, draughts or air vents. Turn air conditioning off, and keep doors and windows closed during use.
If you need a quieter environment, set your machine to fan speeds 1-4, or consider selecting Night mode. Your machine will then use its quietest settings, with a dimmed display.
Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifier's speed settings as the temperature changes. For personal cooling in summer, use settings 4-10. In colder periods, enable Diffused mode. It projects air through the back of the machine, to avoid unwanted cooling.
If you're concerned by the brightness of your purifier's LCD display, consider enabling Night mode using your remote control or the Dyson Link app. During operation, a small moon icon indicates that your purifier is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.
If Auto mode is enabled, AUTO will be illuminated on your machine's LCD display. When purifying the air, AUTO will be in white. When the air in the room is purified, it will turn green and your purifier will remain idle until pollutant levels rise.
Your purifier humidifier fan's auto mode is designed to manage the air quality in your home without you having to operate the machine – so it's only on when it needs to be. If you or someone in your home suffer from allergies or respiratory illnesses, we particularly recommend using Auto mode.
Your purifier works most efficiently in a sealed environment – opening the windows can allow more pollutants to enter the air in your home, which means your machine will take longer to work.
