How to use your purifier
Understanding the LCD screen icons
The icons on your LCD screen show which pollutants are present, reporting them in real time. They also tell you about temperature, humidity and filter life.
Indoor Air Quality Index (AQI)
Shows your air quality over the last 12 seconds, or over the last 24 hours.
Particulate matter PM2.5
Shows microscopic particles smaller than 2.5 microns, including smoke, bacteria and allergens.
Particulate matter PM10
Shows particles smaller than 10 microns, including pollen, dust and pet dander.
Shows particles of formaldehyde, a volatile gas that can emit for years from household flooring and furniture.
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.
Nitrogen Dioxide (NO2)
Shows oxidising gases such as NO2, released by combustion. Includes cigarette smoke, car emissions, candles and gas stoves.
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.
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.
