When your Pre-filter Indicator Light turns on, it’s time to replace your pre-filter. It should
be replaced at least every 3 months. If there are heavy concentrations of odors, smoke, or
large particles in the home, you may need to change the carbon pre-filter more often. For
instructions on how to replace your pre-filter, refer to section “Removing/Changing the
Filters” in this manual.
Note: We do not recommend operating the air purifier without the carbon pre-filter.

To Reset Filter Indicator
• Once the filter has been checked and cleaned or
replaced as needed, the filter indicator will need to
be reset.
• With the unit powered on, press and hold the
appropriate filter indicator button down for
approximately 10 seconds until the light turns off
(Fig. 1).
CAUTION: DISCONNECT FROM POWER SUPPLY BEFORE SERVICING
Do not attempt to wash either the carbon pre-filter or the HEPA filter. They are not
washable and washing will damage the filters.
The only two parts requiring any service are the carbon pre-filter and the HEPA filter.
No tools are needed. To remove or change either filter, disassemble the unit as shown
below:
Step 1: Turn the air purifier off and unplug from the wall outlet.
Step 2: To open, gently place the air purifier on its side and unscrew the locking
mechanism located on the bottom of the unit (Fig. 2).
Step 3: Remove the base assembly from the air purifier.
