Solutions
There has been no
change in micro
dust
concentration.
• Sensor may be dirty or blocked
by foreign material.
• Air purifier may be in enclosed
area.
• See instructions for cleaning sensor.
• Indoor air quality may stay the same in
an enclosed area.
The fine dust
concentration
value keeps
showing high.
• Air purifier installed in area
with constant influx of outside
air.
• Levels can remain high in areas where
there is a constant influx of outside air.
Air quality light
remains
red/orange while
PM levels show
low/normal.
• Air quality issue is from odor.
• The air quality indicator is an overall
evaluation based on odor and dust. If
an odor is strong while PM levels are
low, the light may remain on
red/orange.
The air quality
indicator differs
from the EPA
guide.
• The air purifier and EPA air
quality values are measured
differently.
• The EPA guide indicates an average
value during a given time period and
the air purifier's air quality indicator
measures and displays on a real-time
basis.
The filter produces
odors.
• The deodorizing filter has
become dirty.
• The air purifier is being used
instead of a vent hood while
cooking.
• Replace the filter. Filter life-expectancy
can vary based on usage environment.
• Filter life can be greatly reduced if the
air purifier is used while cooking
strong-smelling or oily food. Do not
use the product in place of a vent
hood. Ventilate the area during
cooking to remove strong odors and
oily splatter, then use the air purifier to
eliminate any remaining odors.
