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
life of your filters. 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
The Pre-Filter and Filter indicators will turn on when the filters need to be replaced.
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. Refer to Changing the Pre-Filter (pg. 9) or Changing the Filter (pg. 10)
for instructions on how to reset the counters.
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 Support, 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 HEPAtech® filter as they pass through
the HEPAtech® Air Purification 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 turn on.
2.To turn the Ionizer off, press the Ionizer key. The Ionizer Indicator will turn off.
When the Ionizer is on, the amber LED will remain illuminated.
