Your air monitor will display four different categories of LED light indications. Green indicates your air quality is managed in that space. Yellow indicates you may have a small source or activity in the space that is generating particulates, odors or chemicals. Green and yellow LED lights are considered normal for most of the time. Orange indicates a medium source, activity or event nearby may be generating particulates, odors or chemicals. Red indicates a large source or event nearby may be generating particulates, odors or chemicals. Orange and red indications should be less common in frequency and duration. Watch and understand your home air quality trends to know best how to manage the air in your space if you see consistent poor air quality readings.
