The overall air quality is calculated based on the concentration of particulates and is categorized in 4 levels based on the level of pollution in the air. (Green, Yellow, Orange, and Red)
Color | Overall air quality | Concentration of PM (μg/m3) | ||
|---|---|---|---|---|
State | PM10 | PM2.5 | PM1.0 | |
Red | Poor | 255 or more | 56 or more | 56 or more |
Orange | Unhealthy | 155 ~ 254 | 36 ~ 55 | 36 ~ 55 |
Yellow | Moderate | 55 ~ 154 | 13 ~ 35 | 13 ~ 35 |
Green | Good | 54 or less | 12 or less | 12 or less |
Overall air quality can be seen by the color of the air quality indicator.
The color of the overall air quality indicator is determined based on the concentration of particulate matter (PM).
PM concentration values are based on the data sheet provided by the sensor manufacturer.
The PM concentration measurement was tested using LG Electronics’ standard test materials.
