Air Quality Indicator
Memory Function
Chart C
Outside of Auto Mode, the air quality indicator will also light up to
denote the current air quality during normal operation. [Chart C]
The air purifier will remember its programmed settings when
turned o and resume these settings when turned back on.
NOTE: The memory function will not remember the programmed time.
NOTE: It will take 30 seconds for the air purifier to detect the air quality
each time it is turned on. The air quality indicator will always light
up blue when the air purifier is first turned on. After 30 seconds,
the color of the indicator will change based on the detected air
quality.
Indicator Color Air Quality
Blue Very Good
Green Good
Orange Moderate
Red Bad
KEEPING THINGS CLEAN
This indicator will light up red to remind you to check the air filter.
How soon turns on depends on how often you use your air
purifier. It does not necessarily mean it is time to change the filter.
Change Filter Indicator
It is recommended that you change the air filter every 6–8 months.
However, the time may vary depending on the frequency of use
and the air quality in the room. It is important to watch out for the
following signs of an expired filter:
• Increased operating noise
• Decreased airflow
• Clogged filter
• Increased presence of odors
NOTE:
• The environment in which the air purifier is being used may also
extend or shorten the lifetime of the air filter. Using your air purifier in
an environment of relatively high pollution may mean you will need to
change the air filter more often.
• If the air pollution in your environment is very high, there is a possibility
that the filter may not be completely eective and may need to be
replaced before the indicator lights up on the display.
• Remember to reset the air purifier after changing the air filter.
When Should I Replace the Air Filter?
NOTE: It is recommended to clean the pre-filter with a brush or vacuum
each month to prevent buildup of hair or dust.
