Air Purifier Maintenance
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.
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
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 filtra
-
tion 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. 16) 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.

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.
Changing the Filter
When the filter exceeds 2800 hours (approximately 4 to 6 months of use), the Filter
indicator will turn on as a reminder that you should replace the filter. (Refer to Filter
Life Counters for additional information, pg. 8.) This is a reminder that you should
check the Filter and replace if necessary. The proper time to change the Filter de
-
pends on usage and the environment. Use the following list to help determine if the
filter should be changed:
• Compare the color of the Filter to the color coded chart on the inside of the hous
-
ing. If the Filter color matches the darkest color on the chart, you should replace
the Filter.
• If you notice a decrease in air output or an increase in noise at any time during
normal operation, the Filter may be clogged. Replace the Filter to return to normal
operation.
