How to use your machine

  • Real-time air quality reports

    With real-time air quality reports on the LCD screen, the Dyson Pure Cool™ purifying fan detects and reports harmful pollutants in the air.

  • LCD display

    The built-in LCD screen shows you gases and particles present in the room, in real time.1

  • Setting airflow speed

    Monitors your air quality, and reacts accordingly.

  • Setting the oscillation angle

    Set the oscillation angle of your purifying fan, from 45° to 350°.

  • Night-time mode/sleep timer

    Set Night-time mode for purified air on the machine's quietest settings, with a dimmed screen. Set a sleep timer to turn your purifying fan off, for any time between one hour and eight hours.

  • Filter life monitoring and maintenance

    Your purifying fan will notify you on the screen or through the app when either of your filters need replacing. Simply click the old one off and a new one on.²

Live air quality reports on the LCD display

The built-in LCD screen shows you which gases and particles are present in the room, right now.1

  • Indoor Air Quality Index (AQI)

    Shows your current indoor air quality.

  • Particulate matter PM 10

    Shows particles smaller than PM10, including pollen, dust and pet dander.

  • Particulate matter PM 2.5

    Measures microscopic particles smaller than PM2.5, including smoke, bacteria and allergens.

  • Nitrogen Dioxide (NO2)

    Potentially harmful gas, released by combustion. Includes cigarette smoke, candles, and gas stoves.

  • Volatile Organic Compounds (VOCs)

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

  • Filter life

    Shows how much filter life remains on both the HEPA and Active carbon fiters, so you know which one to replace, and when.

The Dyson Air Quality Index

To develop the Dyson Pure Cool™ purifying fan, Dyson reviewed numerous international air quality levels. Dyson air quality index (AQI) levels are based on this research and measured in micrograms per feet cubed. For VOCs and NO2 (plus other oxidising gases) Dyson conducted research in both labs and real homes to calibrate the AQI for actual pollution events seen in homes. The data gathered was used to calibrate the Dyson AQI levels to allow the Dyson Pure Cool™ purifying fan to have the appropriate response level to cover these VOCs and NO2 (plus other oxidising gases).

  • Fair

    Your machine is detecting a moderate level of microscopic particles and VOCs.

  • Good

    Your machine is detecting a very low level of microscopic particles and VOCs.

  • Very poor

    Your machine is detecting a very high level of potentially harmful microscopic particles and VOCs. You should run your purifier at a high speed or set it to Auto mode.

  • Poor

    Your machine is detecting a high level of potentially harmful microscopic particles and VOCs. You should run your purifier at a medium to high speed or set it to Auto mode.
