Checking Air Quality

The overall air quality is indicated by color in the status display panel and the air quality indicator light.

Understanding Overall Air Quality

The overall air quality is indicated using four levels, each using a different color. The overall air quality depends on both the

dust density and the odor level.

Overall air quality Dust density (µg/

) Odor level

Color Status PM 10 PM 2.5 PM 1.0 Status 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

• Overall air quality is indicated by the color of the icon in the status display panel and of the air quality indicator

light.

• The overall air quality color indicates the worst level, either the dust density or the odor level.

Using the Air Quality Indicator Light

The overall air quality light changes color to green (good),

yellow (moderate), orange (unhealthy) or red (poor) depending

on the dust density and odor level.

Note

After initial startup, the dust sensor stabilizes for 30 seconds and

the odor sensor stabilizes for two minutes. The air quality light is

white for 30 seconds, then it changes color to indicate the dust

density level. Two minutes after starting, the light may change

again if the odor level is worse than the dust density level.
