Cleaning Your Air Purier
Proper maintenance of your Hunter Air Purier will help ensure years of trouble free
service.
Follow these steps to properly maintain your air purier:
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. 11 and
12) to determine when and how to replace the lters.
NOTES:
• The air purier 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. 8), the Pre-Filter Life Counter will display 0% life remaining and the Pre-Filter
indicator will ash 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 o and unplug the air purier.
2. Next, remove the front grill. Place your ngers in the recesses on either side of
the top of the grill and pull rmly.
3. The pre-lter is attached to the inside of the grill with hook tape. Pull gently on
the pre-lter to remove it.
4. If needed, use a soft damp cloth to wipe o 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 o the pre-lter. Those particles are part of the odor-removing activated
carbon and will be collected on the lter during regular use.
