4 Using the Air Performer
Understanding the air quality bar
The air quality bar automatically goes on when the Air Performer is switched on,
and lights up all colors in sequence. After approximately 30 seconds, the particle
sensor selects the color that corresponds to the surrounding air quality of airborne
particles.
The color of the air quality light is determined by PM2.5 (particles smaller than 2.5
microns). Relative Humidity (RH) level is only available through the app.
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
fine particles are tobacco smoke, cooking, and burning candles. Some airborne
bacteria and the smallest mold spores, pet allergen and dust mite allergen
particles also fall under PM2.5.
