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 Changing the Filter (pgs. 9 and 10) 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 information,
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 HEPAtech® filter. Refer to Obtaining Replacement Filters (pg. 14) if you need help finding
replacement filters.
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 (pg. 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.
6. Place the Front Grill back onto the unit. First, line up the tab on the bottom of the Grill with the
recess on the purifier base and then push the top of the Grill forward until it is closed. Refer
to Figs. 6 and 7 (pg. 7). NOTE: This unit will not operate unless the Grill is in the correct
position.
7. Plug in the Air Purifier.
8. To reset the counter to zero hours and turn off the indicator, simply press and
hold
the Pre-Filter reset key for three seconds. Then, you must release the reset key and
then press and hold the Pre-Filter reset key again for three seconds to turn off the
filter indicator.
