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 de-
pends on the environment, the table below gives typical usage times of the filters.
Table 2: Typical Usage Times of the Filters
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. Refer to Changing the Pre-Filter (pg. 10) or Changing the Filter
(pg. 11) for instructions on how to reset the counters.
