  • What do the different colour lights in my air purifier mean?

Applies to

  • Air Purifier

Solution

  • The air quality indicator will show the real-time indoor air quality level through the use of different colours.
  • The unit is equipped with an air quality sensor(s). The laser-based particulate matter (PM) sensor is a high precision particle sensor that can detect PM1, PM2.5 and PM10 levels. The air quality indicator will visually – with the aid of a colour scale - show the real-time air quality as per table below.
  • When in SMART mode, the air quality level will also determine the fan speed as per table below.
