The built in dust sensor detects the particles concentrations in the air, displaying it by PM2.5 data
shown on top panel as well as the different color LED lights. There are total 6 different LED light
colors to indicate the air quality from good to not good: blue-light blue-green-yellow-pinky purple-
red.
•
If PM 2.5 data is between 0~50 that represents a lower level of PM 2.5 in the air, which means the
quality level is good. If PM2.5 data is between 300~500 that represents a very high level of PM2.5 in
the air, which means the quality level is poor.

mobile applications. All parameters are only for reference, and parameter may also
change on the same product with different fan speeds.
