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 change the filters, your Hunter Air Purifier has Filter Life Counters that will
monitor the life of your filter. Although the exact life of the filters depends on the environ-
ment, 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. 10) or Changing the Filter
(pg. 11) for instructions on how to reset the counters.
