All Winix air purifiers use color codes to indicate air quality. These color codes are:
- Blue light. Means very good air quality. If your Winix PlasmaWave air purifier is set to auto mode it will run a low speed.
- Amber light. Means fair air quality.
- Red light. Means bad air quality as the sensor has detected many airborne pollutants in the air. The air purifier should run at a maximum speed in this case.
These color charts are the same for all Winix air purifiers including C535, 5300-2, 5500-2 and others.
P.S. If your Winix blinking red and the source of this is filter indicator, you should replace the air filter and reset the light.
