Filter Life Counters
The pre-lter and lter are critical to the proper operation of the air purier. To help you
know when to change the lters, your Hunter Air Purier has Filter Life Counters that will
monitor the percentage of life your lter has left. Although the exact life of the lters de-
pends on the environment, the table below gives typical usage times of the lters.
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 Cleanable Filter Life Counters are stored in the air purier’s
memory. The unit may be unplugged and moved or stored without losing the Pre-Filter
and Cleanable Filter Counter values.
To properly track lter usage, the Pre-Filter and Cleanble Filter Life Counters should be reset
each time the lters are changed. Refer to Changing the Pre-Filter (pg. 10) or Cleaning the
Filter (pg. 11) for instructions on how to reset the counters.
