BreatheSmart 75i V2 - Troubleshooting - Particle Sensor Light Not Changing Colors

If your 75iv2 particle sensor light is not changing colors:

The Colors and Their Meaning:

• Blue - Very low level of airborne particles detected
• Green - Low level of airborne particles detected
  
• Orange - Medium level of airborne particles detected
• Red - Significant level of airborne particles detected
• Purple - Very significant level of airborne particles detected

Has anything changed in the room recently that could be producing a significant amount of air particles?

Examples: Do you have a candle burning?, Do you have a Humidifier running in the same room as the Purifier?, The heat turning on or A/C running can affect air quality, Is the purifier in or near the kitchen (open concept great room with kitchen connecting to a living room) and you're cooking or recently were cooking?, Do you have any windows open?, Did you recently paint the room the Purifier is in or have new carpet installed in the room the Purifier is in recently? Etc.

Additional information: Can I use a humidifier with the purifier?

We recommend placing the purifier in a small room or closet that doesn't get a lot of traffic for 48 hours. In that time, periodically check to see if the particle indicator light changes. If it doesn't change, please follow the troubleshooting steps listed in this article.
