Checking the Air Filters

When the change filter icon lights up, this is simply a
reminder to check the air filters. The icon turns on sooner
or later depending on how often you use your air purifier. It
does not necessarily mean it is time to change the filters.
If the change filter indicator has turned on, please
remember to reset the air purifier after checking the filters
by pressing the black reset button inside the vent on the
side of the air purifier (See Resetting the Air Purifier see
page 13).

When Should I Replace the Air Filters?

It is recommended to change the air filters every 6–8
months. However, you may need to change your filters
sooner or later depending on how often you use your air
purifier. It is important to watch out for the following signs of
expired filters:
• Increased operating noise
• Decreased airflow
• Clogged filters
• Increased presence of odors
NOTE:
• The environment in which the air purifier being used
may also extend or shorten the lifetime of the the
air filters. Using your air purifier in an environment of
relatively high pollution may mean you will need to
change the air filters more often.
• If the air pollution in your environment is very high, there
is a possibility that the filters may not be completely
effective and may need to be replaced before the
indicator appears on the display.
• Remember to reset the air purifier after changing the
air filters.
