What does the Air Quality Indicator light color mean?

The Air Quality Indicator light illuminates the floor beneath the unit and shows the current VOC level in the room. Green means Good air quality (low VOC levels), Yellow means Moderate air quality, and Red means Poor air quality with an elevated level of VOCs detected. Upon startup, the light may pulse through all three colors for a few minutes while the unit calibrates before settling on a solid color. (Page 6)
