Checking the Air Quality
You can check the cleanliness of the indoor air by looking at the light of air quality and the status
display panel.
understanding the Overall Air Quality
The overall air quality is calculated based on the particles and odour (gas) concentrations
and is categorized into 4 levels including green, yellow, orange or red depending on the
contamination of the air.
Color

Quality
Concentration of PM (μg/m

PM10
(coarse particles)
PM2.5
(fine particles )
PM1.0
(particles with a
diameter between 1.0
and 2.5 µm)
State Level
red Poor 255 or more 56 or more 56 or more Very strong 4
Orange unhealthy 155~254 36~55 36~55 Strong 3
Yellow Moderate 55~154 13~35 13~35 normal 2
Green Good 54 or less 12 or less 12 or less weak 1

•
The color of overall air quality is determined based on whichever is worse between the
particles concentration and odour (gas) concentration.
•
PM (particulate matter) concentration is displayed in increments of 1 unit, from 8 to 999.
PM concentration values are based on the data sheet provided by the sensor manufacturer.
–
Differences in PM concentration values may be the result of different methods of
measuring or differences in the actual PM concentration levels.
–
The PM concentration measurement was tested using lG electronics’ standard test
materials.
•
The overall air quality level is a result of both PM concentration and the odour level. It may
differ from the PM10, PM2.5 and PM1.0 concentration levels.
