How to Change the Filters

CAUTION: DISCONNECT FROM POWER SUPPLY BEFORE SERVICING.
Do not attempt to wash either the activated 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 activated carbon pre-filter and the
HEPA filter. No tools are needed. To change either filter, disassemble the unit as
shown below:
Fig. 1
Step 1: Turn the air cleaner off and unplug from the wall outlet.
Step 2: To open, gently place the air cleaner on its side and unscrew the locking
mechanism located under the base assembly. (Fig. 1)
Step 3: Remove the base assembly from the air cleaner.
Step 4: Remove the filter assembly (consisting of the HEPA filter and pre-filter) from
the internal chamber.
Step 5: Locate the seam of the pre-filter and carefully separate the fastener to
remove the pre-filter from the HEPA filter (Fig. 2).
Step 6: Discard used filter(s) being replaced. Remove any packaging and plastic
from the replacement filter(s).
Step 7: Carefully wrap the pre-filter around the HEPA filter so that the ends meet
(Fig. 3). Fasten the ends together with the fastener provided.
Step 8: Place the whole filter assembly into the internal chamber. Close the product
by replacing the base and tightening the locking mechanism.
Step 9: Turn the air cleaner into an upright position, plug into a wall outlet and it is
ready for operation.
Storage
If you store your Honeywell HEPA air cleaner for more than 30 days, we recommend:
• Remove both the primary HEPA filter and the activated carbon pre-filter from
the unit.
• Discard the pre-filter.
• Wrap the HEPA filter in an air-tight plastic bag or plastic wrap. Be sure that
the filter is totally sealed to protect it from its storage environment.
• To restore the air cleaner to service, unwrap the HEPA filter, install a new
activated carbon pre-filter, and replace both filters in the air cleaner. See
"How to Change the Filters" section for proper installation.
