Filter Life Counters

The pre-lter and lter are critical to the proper operation of the air purier. To help you
know when to change the lters, your Hunter Air Purier 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 puriers
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.
