Cleaning Your Air Purier
Proper maintenance of your Hunter Air Purier will help ensure years of trouble free ser-
vice.
Follow these steps to properly maintain your air purier:
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-lter 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 lters.
NOTES:
• The air purier 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-lter. To maintain proper odor-removing capability and overall ltration performance, the
pre-lter should be changed every 1400 hours (approximately 3 months of use). If necessary,
the pre-lter can be changed more often. Proper maintenance of the pre-lter will help extend
the life of the HEPAtech

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