REMOVING/CHANGING THE FILTERS
CAUTION: DISCONNECT FROM POWER SUPPLY BEFORE SERVICING
Do not attempt to wash either the odor reducing pre-filter or the HEPA filter. They
are not washable and washing will damage the filters.
The only two parts requiring any service from you are the odor reducing pre-filter and
the HEPA filter. No tools are needed. To remove or change either filter, disassemble the
unit as shown below:
Fig. 2
BEFORE OPERATING THE AIR PURIFIER, MAKE SURE PRE-FILTER IS IN PLACE.
To order replacement pre-filter or filter, refer to the "Accessories and Replacement
Filters" section.
Step 1: Turn the air purifier off and unplug from the wall outlet.
Step 2: To open and gain access to the filter, 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.
Step 4: Remove the filter or filter assembly (consisting of the HEPA filter and pre-filter)
from the internal chamber.
Step 5: If pre-filter is being changed, locate the seam of the pre-filter and carefully
separate the fastener to remove the pre-filter from the HEPA filter (Fig. 3).
Step 6: Discard used pre-filter if necessary. Check the HEPA filter to ensure it is
not too dirty or seems to be clogged. Replace the HEPA filter if necessary.
Step 7: Carefully wrap the pre-filter around the HEPA filter so that the ends meet
(Fig. 4). Fasten the ends together with the fastener provided.
Step 8: Place the whole filter assembly back into the internal chamber. Close the
product by replacing the base and tightening the locking mechanism until snug.
DO NOT OVER-TIGHTEN.
Step 9: Turn the air purifier into an upright position, plug into a wall outlet and it is
then ready for operation.
Do not forget to reset the Intelli-Check™ filter indicator.
