Using your machine

Understanding your LCD screen's 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 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, bacteria and allergens.

  • Particulate matter PM10

    Shows particles smaller than 10 microns, including pollen, dust and pet dander.

  • Volatile Organic Compounds (VOCs)

    Shows gases released from a wide range of sources, such as aerosol sprays and air fresheners. They include formaldehyde and benzene, household fumes and odours.

  • Nitrogen Dioxide (NO2)

    Shows oxidising gases such as NO2, released by combustion. Includes cigarette smoke, car emissions, candles and gas stoves.

  • Filter life

    Shows how much filter life remains on the combination filter. So you know when to replace it.

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.

  • The LCD screen's icons showing different levels of pollutants

    Good

    When the green section of the coloured bar is highlighted, your machine is detecting a very low level of the type of pollutant.

  • The LCD screen's icons showing different levels of pollutants

    Fair

    When the yellow section of the coloured bar is highlighted, your machine is detecting a moderate level of the type of pollutant.

  • The LCD screen's icons showing different levels of pollutants

    Poor

    When the orange section of the coloured bar is highlighted, your machine is detecting a high level of the type of pollutant.

  • The LCD screen's icons showing different levels of pollutants

    Very poor

    When the red section of the coloured bar is highlighted, your machine is detecting a very high level of the type of pollutant.

  • Auto mode

    In Auto mode, your machine monitors and responds to air pollution. When it detects pollutants, it automatically projects purified air.

  • Oscillation angle

    You can set the oscillation angle of your purifying fan, from 45° to 350°.

  • Airflow speed

    Choose from 10 different fan speed settings, and switch between front projection and Diffused modes.

  • Person scheduling their machine using the Dyson Link app

    7-day scheduling

    Choose when you want your machine to be on and off, up to seven days in advance, with the Dyson Link app.

  • The Dyson Pure Cool Cryptomic air purifier in Night mode

    Night mode

    For the quietest settings and a dimmed display, set your machine to Night mode using your remote control.

  • Person setting the Sleep timer using the remote control

    Sleep timer

    At night, you can set the sleep timer for between 30 minutes and 8 hours. So you can keep cool and comfortable while you rest.

Maintaining your machine

You can find out how to monitor and replace the combination filter in our video guide. Your Dyson Cryptomic™ filter is permanent, so you don’t need to change it.

FAQs

The combination filter needs to be changed after 12 months, based on 12 hours’ use a day. The Dyson Cryptomic™ filter is permanent, so you don’t need to change it.

If you're concerned by the brightness of your air purifier fan'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.

If auto mode is enabled, AUTO will be illuminated on your purifying fan'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 purifying fan will remain idle until pollutant levels rise.

Your air purifier​ 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 your machine's auto mode.

Your air purifier fan​ is engineered to purify single rooms, so you should use it where you spend the majority of your time at home. 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.

Your air purifier fan​ 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.

Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your air purifier fan'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.
