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 environment, the table below gives typical usage times of the filters. Table 2: Typical Usage Times of the Filters Filter Type Activated Carbon Pre-Filter PermaLife® Filter Typical Usage 1400 hours 2800 hours 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 Cleaning the Filter (pg. 11) for instructions on how to reset the counters. Resetting the Air Purifier In the unusual situation that the unit or the display is exhibiting erratic behavior, you may want to reset the air purifier. If you still have problems after resetting the air purifier, please contact Hunter for additional assistance (refer to Technical Support, pg. 14). To Reset the Air Purifier: 1. Unplug the unit for at least 30 seconds. 2. Plug the unit back in. 41555-01
