The Air Quality Sensor
(select models only)
The air quality sensor is a rectangular
compartment located on the side of
the air purifier. It contains both the
sensor/sensor lens and the sensor
cleaner (see Fig. 1). The sensor cleaner
is soft and specially shaped to fit inside
the sensor/sensor lens area. Monthly
cleaning of the sensor/sensor lens is
recommended. Cleaning the Sensor/
Sensor Lens:
1. Open the compartment door and
remove the sensor cleaner. If sensor
cleaner is difficult to grasp, pull on
the black ribbon underneath to help
release it.
2. Holding one end of the sensor clean-
er, push the piece in and out of the
sensor/sensor lens opening several
times. This will clean the area.
3. Slide the sensor cleaner back into its
storage compartment and close the
air quality sensor door. Make sure
the compartment door is fully closed
or the air purifier may not operate
properly.

*Each air purifier is designed to filter
the room air five times per hour at
high speed. Factors such as room
shape and ceiling height can affect
this rate. It is normal that the air
flow will be reduced as the filter
becomes clogged. Replace the
HEPA filter as needed.
