Understanding the LCD screen
Air quality graph
Shows your air quality over the last 12 seconds, or over the last 24 hours.
Shows microscopic particles smaller than 2.5 microns, including smoke, bacteria and allergens.
Shows particles smaller than 10 microns, including pollen, dust and pet dander.
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.
When the green section of the coloured bar is highlighted, your purifier is detecting a very low level of the type of pollutant.
When the yellow section of the coloured bar is highlighted, your purifier is detecting a moderate level of the type of pollutant.
When the orange section of the coloured bar is highlighted, your purifier is detecting a high level of the type of pollutant.
When the red section of the coloured bar is highlighted, your purifier is detecting a very high level of the type of pollutant.
Filter care for optimum performance.
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.
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.
