Cleaning Your Air Purifier
Proper maintenance of your Hunter Air Purifier will help ensure years of trouble free ser-
vice.
Follow these steps to properly maintain your air purifier:
1. Approximately every 90 days, the outside of the unit should be cleaned with a soft, damp
cloth.
2. If needed, the front grill can be removed from the unit and cleaned with soapy water.
Simply remove the pre-filter before exposing the grill to water.
3. Follow the instructions in Changing the Pre-Filter and Changing the Filter (pgs. 10 and
11) to determine when and how to replace the filters.
NOTES:
• The air purifier must be unplugged during the cleaning process.
• Be sure the unit is completely dry before plugging in and using.
• Never immerse unit in water.
Changing the Pre-Filter
When the Pre-Filter exceeds 1400 hours (refer to Filter Life Counters for additional informa-
tion, pg. 8), the Pre-Filter indicator will turn on as a reminder that you should replace the
pre-filter. To maintain proper odor-removing capability and overall filtration performance, the
pre-filter should be changed every 1400 hours (approximately 3 months of use). If necessary,
the pre-filter can be changed more often. Proper maintenance of the pre-filter will help extend
the life of the

filter. Refer to Obtaining Replacement Filters (pg. 13) if you need
help finding replacement filters.
To change the pre-filter and reset the Pre-Filter Life Counter:
1. First, turn off and unplug the air purifier.
2. Next, remove the front grill. Place your fingers under the handle on the grill
and pull forward, then up. Refer to Figs. 4 and 5 (pg. 6).
3. The pre-filter is attached to the inside of the grill with hook tape. Pull gently
on the pre-filter to remove it. Refer to Fig. 9.
4. If needed, use a soft damp cloth to wipe off the grill.
5. Install the new pre-filter by placing it in the grill and pressing gently on the pre-
filter so that it adheres to the hook tape. You may notice a few black particles
coming off the pre-filter. Those particles are part of the odor-removing activated
carbon and will be collected on the filter during regular use.
