It’s on auto mode and the sensors are detecting poor air quality around it.
Sorry, there was a problem. Please try again later.If it's always red - then there might be a problem with the unit. However if when you unplug the unit it starts out blue and then changes to red it means something is in the air. I've notice certain food smells and other relatively minor things will immediately change mine to red even though it's not actually an air "quality" problem as far as I'm concerned. Let it run for awhile and it should clear the air. If you're smoking in the room or something like that - it might stay on red because it's continually reading the smoke.
