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 percentage of life your filter has left. 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
Filter Type | Typical Usage |
| |
Activated Carbon Pre-Filter | 2000 hours |
| |
HEPA Filter | 8000 hours |
| |
The display shows the percentage of life left since the counter was reset. NOTE: The percentage 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. 9) or Changing the Filter (pg. 10) for instructions on how to reset the counters.
