Understandingtheairqualitylight
The air quality light automatically goes on when the appliance is switched on, and lights up all colors in
sequence. After approximately 30 seconds, the particle sensor selects the color that corresponds to the
dierent working modes.
The color of the air quality light is determined by the highest index among PM2.5 and IAI readings.

Humidity
Humidity normally refers to relative humidity, it means the amount of water vapor in the atmosphere.
Humidity dierence ( % ) refers to the variance between the target humidity and current ambient
humidity.

PM2.5
AeraSense sensing technology accurately detects and quickly responds to even the slightest particle
change in the air. It provides you with reassurance with real-time PM2.5 feedback.
Most of the indoor air pollutants fall under PM2.5 – which refers to airborne particle pollutants smaller
than 2.5micrometers. Common indoor sources of ne particles are tobacco smoke, cooking, burning
candles. Some airborne bacteria and the smallest mold spores, pet allergen and dust mite allergen
particles also fall under PM2.5.

IAI
The professional-grade AeraSense sensor detects the level of indoor air allergen and with numerical
feedback from 1 to 12 the potential risk level of indoor air allergens can be displayed. 1 indicates best
air quality.
