How to use your purifier heater

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, 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 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 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 coloured bar on the left indicates how much of the pollutant is present, and will continually update as the machine purifies your air.

  • Good pollutant levels screen

    Good

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

  • Fair pollutant levels screen

    Fair

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

  • Poor pollutant levels screen

    Poor

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

  • Very poor pollutant levels screen

    Very poor

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

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 heater'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 heater'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 heater is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.

How do I know when my purifier heater is in Auto mode?

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

How long should my purifier heater be turned on for?

Your purifier heater'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.

Where should I place my purifier heater?

Your purifier heater 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.

Should I keep my windows open or closed?

Your purifier heater 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.

How often do the filters need to be changed?

The HEPA+Carbon filter needs to be changed after 12 months, based on 12 hours’ use a day.
