How to use your purifier
Understanding the LCD screen icons
The icons on your LCD screen show which pollutants are present, reporting in real time. The icons also tell you about temperature, humidity and filter life.
Indoor Air Quality Index (AQI)
Shows your air quality over the last 12 seconds, or over the last 24 hours.
Particulate matter PM2.5
Shows microscopic particles smaller than 2.5 microns, including smoke and allergens.
Particulate matter PM10
Shows particles smaller than 10 microns, including pollen, dust and pet dander.
Shows particles of formaldehyde, a potentially harmful gas that can emit for years from common household items such as flooring, furniture and fabrics.
Volatile Organic Compounds (VOCs)
Shows gases released from a wide range of sources, such as aerosol sprays and air fresheners. They include benzene, household fumes and odours.
Nitrogen Dioxide (NO₂)
Shows oxidizing gases such as NO₂, released by combustion. Includes cigarette smoke, car emissions, candles and gas stoves.
Shows how much filter life remains on the HEPA+Carbon filter. So you know when to replace it.
Understanding pollutant levels
When a pollutant reduces your air quality, its icon appears on screen. In this case, PM10. The colored bar on the left indicates how much of the pollutant is present, and will continually update as the machine purifies your air.
When the green section of the colored bar is highlighted, your purifier is detecting a very low level of the type of pollutant.
When the yellow section of the colored bar is highlighted, your purifier is detecting a moderate level of the type of pollutant.
When the orange section of the colored bar is highlighted, your purifier is detecting a high level of the type of pollutant.
When the red section of the colored bar is highlighted, your purifier is detecting a very high level of the type of pollutant.
Using the remote control
Maintaining your purifier
To ensure optimum air purification performance, we recommend replacing your HEPA+Carbon filter every 12 months. Your machine will alert you when your filter needs replacing. Your Catalytic filter never needs replacing.

Frequently asked questions
Should I change the fan settings in different seasons?
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.
Does the LCD display stay on throughout the night?
If you're concerned by the brightness of your purifier's LCD display, consider enabling Night-time 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.
How do I know when my purifier is in Auto mode?
If auto mode is enabled, AUTO will be illuminated on your purifier's LCD display. When your machine is 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.
How long should my purifier be turned on for?
Your purifier's auto mode is designed to manage the air quality in your space without you having to operate the machine – so it's only on when it needs to be.
Where should I place my purifier?
Dyson Experts are on hand to better understand your business environment and can advise about where to place your purifier to best suit your space. When placing the machine, make sure there is at least a few feet of clearance on all sides so that the air can circulate effectively.
Should I keep my windows open or closed?
Your purifier works most efficiently in a sealed environment – opening the windows can allow more pollutants to enter the air inside, which means your machine will take longer to work.
How often do the filters need to be changed?
The formaldehyde-destroying catalytic filter never needs replacing. And we recommend replacing the HEPA+Carbon filter every 12 months (based on 12 hours a day of use) – so this may vary depending on usage and pollution levels. You'll be notified via the Dyson Link app or LCD screen when it's time to replace it.
Do I need to maintain my purifier's filter?
No, unlike some conventional filters which require changing, washing and drying each month, this isn't the case with ours. So there's no time wasted without a working purifier. Our filter is quick and easy to replace – and you'll know exactly when, via the Dyson Link app or LCD screen. Please note that the selective catalytic oxidisation filter never needs replacing.
