How to use your machine

  • Dyson Pure Cool LCD air quality

    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.

  • Dyson Pure Cool LCD display

    LCD display

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

  • Dyson Pure Cool airflow speed

    Setting airflow speed

    Monitors your air quality, and reacts accordingly.

  • Dyson Pure Cool tower oscilation

    Setting the oscillation angle

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

  • Dyson Pure Cool tower Night-time mode

    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.

  • Dyson Pure Cool filter changing

    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.

Cleaner indoor air, day after day

Over time, purifier filters can get clogged up with microscopic pollutants, and even let unpleasant odours back into the room. That's why we recommend changing your filter when your machine alerts you - so it keeps on running effectively, for a cleaner environment.

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).
