4 Using the air purifier
Understanding the air quality light
The air quality light automatically goes on when the air purifier 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.
| Air quality light color | Air quality level |
| Blue Good | |
| Blue-purple Fair | |
| Purple-red Poor | |
| Red Very poor |
The color of the air quality light is determined by the highest risk among PM2.5, IAI and Gas readings.
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.
| PM2.5 level Air quality light color | |
| ≤35 Blue | |
| 36-75 Blue-purple | |
| 76-115 Purple-red | |
| >115 Red | |
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, 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.
GAS
With an advanced gas sensor, a display ranging from L1 to L4 shows the level change of potential harmful gases (incl. VOC, odor, etc.) detected. L1 indicates best air quality.
| IAI level | Air quality light color |
| 1-3 Blue | |
| 4-6 Blue | -purple |
| 7-9 | Purple-red |
| 10-12 | Red |
| Gas level | Air quality light color |
| L1 Blue | |
| L2 | Blue-purple |
| L3 | Purple-red |
| L4 | Red |
