Introduction
Thank you for purchasing the QuietFlo® HEPA 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 HEPA filter will remove 99.97% of 0.3 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 HEPA filter.
• 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 the filters, the pre-filter and HEPA filter, the unit has built in
life counters that keep track of the life remaining of each filter.

Description of Air Filtration System
How the QuietFlo® HEPA 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 HEPA filter where the smaller particles are
collected. Finally, the clean purified air is released back into the room.

Operation
Initial Operation
This section provides basic instructions on the use of your air purifier. After following these
initial directions, please continue reading this booklet to learn how to operate the more
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, open
the front grill by placing your fingers under the handle and pulling the front grill
towards you. The front grill will rest open at about 45º. You can remove the front
grill by placing your fingers under the handle and pulling the front grill towards
you and then up.

3. Next, check the HEPA filter by pressing firmly on all four corners of the filter to
ensure that it is fully inserted into the filter opening.
4. The carbon pre-filter is mounted inside the front grill with hook tape. Confirm
that it properly covers the grill vents. 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 use.
5. Place the front grill back onto the unit. First, line up the tabs on the bottom of
the grill with the openings on the purifier base and then push the top of the
grill forward until it is closed. NOTE: This unit will not operate unless the
grill is in the correct position.

Fig. 7
Filter Life Counters
The pre-filter and filter are critical to the proper operation of the air purifier. To help you
know when to 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
2000 hours
HEPA Filter
8000 hours
The display shows the percentage of life left since the counter was reset. NOTE: The percentage 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 PreFilter 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. Refer to Changing the Pre-Filter (pg. 9) or Changing the Filter
(pg. 10) for instructions on how to reset the counters.

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. 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 2000 hours (refer to Filter Life Counters for additional information, pg. 7), 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 2000 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
HEPA filter. Refer to Obtaining Replacement Filters (pg. 11) 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 in the recesses on either side of the
top of the grill and pull firmly.
3. The pre-filter is attached to the inside of the grill with hook tape. Pull gently on
the pre-filter to remove it.
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.

6. Install the grill back onto the unit. First, line up the tabs on the bottom of the grill
with the openings on the purifier base and then push the top of the grill forward
until it is closed.
7. Plug in the air purifier. NOTE: This unit will not operate unless the grill is in the
correct position.
8. Finally, reset the Pre-Filter Counter by pressing the PRE-FILTER RESET
key for 2 seconds. The Pre-Filter Counter will return to 100% and the PreFilter indicator will stop flashing.
Changing the Filter
When the filter exceeds 8000 hours (approximately 1 year 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. 7). This is a reminder that you should check the filter and
replace if necessary. The proper time to change the filter depends 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 housing. 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.
To change 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 in the recesses on either side of the
top of the grill and pull firmly.
3. Gently pull on the filter to remove it from the unit. While removing the filter,
note the directional arrows printed on the side of the filter. The new filter will be
installed with the same orientation. Once removed, the used filter can be discarded.
4. Remove the new filter from its wrapping and look at the directional arrows
printed on the side of the filter. Install the filter with arrows pointing towards
the unit. Press the filter firmly into the air purifier. To avoid damaging the
filter media, you should press on the frame of the filter only.
5. Reinstall the grill by first lining up the tabs on the bottom of the grill with the
openings on the air purifier base and then pushing the top of the grill forward
until it is closed.
