4 Operation
4.1 Understanding the air quality light ring
The light ring indicates the air quality. It lights up all colours in sequence,
when the air purifier is switched on. After approximately 30 seconds, the
particle sensor selects the color that corresponds to the surrounding air
quality of airborne particles, according to table 2.
PM2.5
PM2.5 refers to ultra-fine airborne particle pollutants smaller than 2.5
micrometers. Most of the indoor air pollutants fall under PM2.5 like:
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.
The air quality sensor scans the air continuously to detect the ultra-fine
particles. This information is reported continuously in both the digital
display and the light ring, providing real-time PM2.5 feedback.
