Introduction
Thank you for purchasing the PermaLife™ Air Purifier from Hunter Fan Company. You have
purchased our latest development in portable air purification which has been designed to improve the quality of the air that you breathe. The following innovative features are included in
your Hunter Air Purifier.
• High Particulate Efficiency: The cleanable filter will remove 99.5% of 0.5 micron particles
from the air that passes through the filter.
• Odor Removal: The activated carbon pre-filter helps remove odors such as cooking, smoke,
and pet smells from the air. It also traps lint, hair, and other large particles to help extend the
life and performance of the cleanable filter.
• Ionizer: The ionizer improves the quality of air in the room by releasing negative ions into
the air that attract positively charged dust, smoke, and pollen particles.
• Quiet: The air purifier has been designed to operate quietly and efficiently. You can choose
among three speeds to best meet your needs at different times.
•Filter Counters: Filter maintenance is critical to the performance of the air purifier. To help
you determine when to change or clean the pre-filter and cleanable filter, the unit has built in
life counters that keep track of the life remaining of each filter.
• NiteGlo™ Light: Your air purifier display has a backlight that is continuously lit as long as
there is power to the unit. You can choose to turn the backlight off or on.

Description of Air Filtration System
How the PermaLife™ Air Purifier System Works
As the air is pulled into the purifier, the activated carbon pre-filter absorbs odors and catches
large particles. Then, the air travels through the PermaLife™ Cleanable Filtration System
where the smaller particles are collected. Then, the ionizer releases negative ions into the air
that attract positively charged dust, smoke, and pollen particles. Finally, the clean purified
air is released back into the room.

advanced features of your air purifier.
Basic Operation of the Air Purifier:
1. Take the air purifier out of the box and remove the clear plastic protective bag.
Place the unit on a firm level floor.
2. Before turning on the air purifier, you need to confirm that the filters are firmly
in place and have not become loose during shipping. To check the filters, first
open the front grill. Release the front grill by placing your fingers under the
handle on the grill and pull forward, then up. Refer to Figs. 4 and 5.
HANDLE

Operation
Filter Life Counters
The pre-filter and filter are critical to the proper operation of the air purifier. To help you
know when to clean or change the filters, your Hunter Air Purifier has Filter Life Counters
that will monitor the percentage of life your filter has left. Although the exact life of the
filters depends on the environment, the table below gives typical usage times of the filters.
Table 2: Typical Usage Times of the Filters
Filter Type Typical Usage
Activated Carbon Pre-Filter 1400 hours
Cleanable Filter 2800 hours
The display shows the percentage of life left since the counter was reset. NOTE: The per-
centage level drops in 5% increments.
The values of the Pre-Filter and Filter Life Counters are stored in the air purifier’s
memory. The unit may be unplugged and moved or stored without losing the Pre-
Filter and Filter Counter values.
To properly track filter usage, the Pre-Filter and Filter Life Counters should be reset each
time the filters are changed or cleaned. Refer to Changing the Pre-Filter (pg. 10) or Cleaning the Filter (pg. 11) for instructions on how to reset the counters.
Locking/Unlocking the Keypad
Once you enter the desired speed, you may want to lock the keypad to prevent accidental
changing of the speed. When the keypad is locked, all keys will be disabled. If you press a
key, the Keypad Locked Indicator will be displayed on the screen for 1-2 seconds.
To Lock or Unlock the Keypad:
1. To lock the keypad, press and hold the UP/DOWN keys
simultaneously for 2-3 seconds. The Keypad Locked Indicator will appear on the display. Refer to Fig. 9. After
releasing the keys, the Keypad Locked Indicator will disappear.
2. To unlock the key pad, press and hold the UP/DOWN
keys simultaneously for 2-3 seconds. The Keypad Indicator will disappear and the keypad will be functional.

Operation
Resetting the Air Purifier
In the unusual situation that the unit or the display is exhibiting erratic behavior, you may
want to reset the air purifier. If you still have problems after resetting the air purifier, please
contact Hunter for additional assistance (refer to Technical Assistance, pg. 14).
To Reset the Air Purifier:
1. Unplug the unit for at least 30 seconds.
2. Plug the unit back in.
Using the Ionizer
Using the ionizer improves the quality of air in the room. Negative ions are released into the
air and positively charged dust, smoke, and pollen particles are attracted to the negative
ions. These particles settle out of the air and can be vacuumed up during normal cleaning.
These particles are also more easily captured by the cleanable filter as they pass through the
PermaLife™ Cleanable Filtration System. To ensure the best air circulation in the room, we
recommend that you place your air purifier six (6) inches away from any walls.
To turn the ionizer on or off:
1. To turn the ionizer on, press the IONIZER key. The Ionizer Indicator will appear on the display. Refer to Fig 10.
2. To turn the ionizer off, press the IONIZER key. The Ionizer Indicator will disappear.
Fig. 10
Controlling the Backlight
Your air purifier display has a backlight that is continuously lit as long as there is power to
the unit. The backlight may be turned off.
To turn the backlight off or on:
Press the PRE-FILTER RESET and FILTER RESET keys at the same time.
NOTE: Do not hold down the keys for longer than 2 seconds. This may reset a

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 Cleaning the Filter (pgs. 10 and
11) 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 information, pg. 8), 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
cleanable filter. Refer to Obtaining Replacement Filters (pg. 13) 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 prefilter 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.

key for 2 seconds. The Pre-Filter Counter will return to 100% and the PreFilter indicator will stop flashing.
Cleaning the Filter
The PermaLife™ Filtration System uses a cleanable filter that never has to be changed, only
cleaned. When the filter exceeds 2800 hours (approximately 4 to 6 months of use), the Filter
Life Counter will display 0% life remaining and the Filter indicator will flash (refer to Filter
Life Counters for additional information, pg. 8). This is a reminder that you should check
the filter and clean if necessary. The proper time to clean the filter depends on usage and the
environment. Use the following list to help determine if the filter should be cleaned:
• Compare the color of the filter to the color coded chart on the inside of the housing. If the
filter color matches the darkest color on the chart, you should clean 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. Clean the filter to return to normal operation.
To clean the filter and reset the 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).
