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 screen

    Indoor Air Quality Index (AQI)


    Shows your air quality over the last 12 seconds, or over the last 24 hours.

  • Particulate matter PM2.5 screen

    Particulate matter PM2.5


    Shows microscopic particles smaller than 2.5 microns, including smoke, bacteria and allergens.

  • Particulate matter PM10 screen

    Particulate matter PM10


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

  • Nitrogen Dioxide screen

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

  • Volatile Organic Compounds screen

    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.

  • Filter life screen

    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.

  • Fair pollutant levels screen

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

  • Good pollutant levels screen

    Good


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

  • Poor pollutant levels screen

    Poor


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

Fitting the filter

FAQs

Frequently asked questions

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

Yes. Your Dyson purifier filter is guaranteed against original defects in materials and workmanship for a period of 12 months from the date of purchase. Filter units that must be replaced because the filter life has expired are not covered by the warranty.

If you're concerned by the brightness of your purifying fan heater's LCD display, consider enabling Night-time mode using your remote control. 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 purifying 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 purifying fan 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.

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