Cleaning Your Air Purifier

Proper maintenance of your Hunter Air Purifier will help ensure years of trouble free
service.
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 Cleaning the Filter (pgs. 11 and
12) to determine when and how to replace or clean 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 infor-
mation, pg. 9), the Pre-Filter Life Counter will display 0% life remaining and the Pre-Filter
indicator will flash 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 HEPAtech® filter. Refer to obtaining Replacement Filters (pg. 14) 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. 11 (pg. 11).
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.
