Arrow - Left Back to Protect

How do I read the air quality indications on my Protect air purifier?

The Protect has built-in particle, VOC, temperature and humidity sensor.

The LEFT indicator light bar on the user panel displays air quality base show the highest pollution level out of PM1, PM2.5 and PM10

The RIGHT indicator light bar on the user panel displays air quality base on VOC measurement.

The light will show one of five colors; red (very polluted), orange (slightly polluted), yellow (moderate), green (good), and blue (excellent) to indicate air quality.

The air quality LED indicator can be turned off by pressing down the setting the air purifier to Night mode, or adjusting the LED brightness setting in the Blueair app.
