Air Quality Sensor Models
1. Air Quality Sensor Display (on
selected models only) – When the
air purifier is first turned on, the Air
Quality Sensor will analyze the air to
determine the current air quality. It
may take up to one minute to acti-
vate the sensor. The sensor will then
continue to monitor and show the air
quality (poor, fair, or good) in a bar
graph in the display.
If the fan is set to Auto, the sensor
automatically adjusts the fan speed
for the most effective air purification.
2. Power On Indicator – Lights when
unit is on.
