Understanding the LCD screen

  • Air quality graph

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

  • PM2.5 level

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

  • PM10 level

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

  • 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 reduces your air quality, its icon appears on screen. In this case, PM10. This coloured bar on the left indicates how much of the pollutant is present, and will continually update as the machine purifies your air.

  • Good

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

  • Fair

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

  • 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

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

    Replacing the HEPA filter

    We recommend replacing the HEPA filter every 12 months, or sooner if needed. Always turn off and unplug your machine. Press both catches on either side of the air amplifier and lift off. Remove the filter and dispose of in a household waste bin. Lower the new filter into place and reassemble your machine.

  • The screw on the bottom of the remote control being removed by a screw driver.

    Replacing the battery

    Start by removing the screw on the back of the remote. After the screw has been removed, push down on the bottom of the remote to release the battery cover. Replace the battery and click the cover back in place, then secure with screw.

Frequently asked questions

We recommend replacing the HEPA+Carbon filter every 12 months. That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen.

No. Some purifiers rely on you changing, washing and drying the filters each month. The time spent waiting for the filter to dry is time without a working purifier. With the Dyson Purifier Cool range, you don’t need to waste time washing and drying the filters. The indicator is designed to remind you when it is time to replace the filters.

Dyson purifiers are optimal when left switched on in Auto mode. This allows the purifier to constantly monitor your air quality, and automatically sense and capture pollutants. It adjusts the airflow speed, only purifying when needed.
