The overall air quality is calculated based on the particles and odor (gas) concentrations and is categorized in 6 levels depending on the contamination of the air. (Green, Yellow, Orange, Red, Pink and Violet)
Color | Overall air quality | Concentration of PM (μg/m3) | Concentration of odor | |||
|---|---|---|---|---|---|---|
State | PM10 | PM2.5 | PM1.0 | State | Level | |
Violet | Severe | 421 or more | 251 or more | - | ||
Pink | Very Poor | 351 ~ 420 | 151 ~ 250 | |||
Red | Poor | 251 ~ 350 | 116 ~ 150 | Very strong | 4 | |
Orange | Unhealthy | 151 ~ 250 | 76 ~ 115 | Strong | 3 | |
Yellow | Moderate | 51 ~ 150 | 36 ~ 75 | Normal | 2 | |
Green | Good | 50 or less | 35 or less | Weak | 1 | |
The color of the overall air quality is based on the worst level detected, whether odors (gas) or particulates.
PM (particulate matter) 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.
Differences in PM concentration values may be the result of different methods of measuring or differences in the actual PM concentration levels.
If the PM concentration is high, there may be a larger difference between the displayed concentration and the actual concentration.
