•
Check the dust particle size display window.
•
Dust density is displayed based on the dust density window with the highest contamination
level.
Example) When PM10 density is 79 (normal), and PM2.5 is 90 (bad), and PM1.0 is
50 (normal), PM2.5 value is displayed for dust density.
Cleanliness is displayed in 4-level color depending on the contamination level of PM10 /
PM2.5 / PM1.0 and odor.
(Contaminated) Red → Orange → Green → Blue (clean)
•
When the displayed cleanliness is above bad/very bad, the cause of bad level (dust/odor) is
displayed in addition to cleanliness color display.
Overall cleanliness color is displayed based on the worst level among PM10 / PM2.5 / PM1.0
and odor.
