AIR QUALITY FRONT PANEL DISPLAY
A precision laser sensor detects your air
quality in real-time, reporting the true
concentration of particulate matter (PM) in
your air. Consistent with the Air Quality Index
set by the EPA, a display on the top of the unit
shows your live PM index reading, while a
light strip on the front panel changes colors
according to your EPA index score, so you can
see the air quality from across the room.
