Cleaning the Filter
he PermaLife™ Filtration System uses a cleanable filter that never has to be changed, only
cleaned. When the filter exceeds 2800 hours (approximately 4 to 6 months of use), the Filter
Life Counter will display 0% life remaining and the Filter indicator will flash (refer to Filter
Life Counters for additional information, pg. 8). This is a reminder that you should check
the filter and clean if necessary. The proper time to clean the filter depends on usage and
the environment. Use the following list to help determine if the filter should be cleaned:
• Compare the color of the filter to the color coded chart on the inside of the housing. If
the filter color matches the darkest color on the chart, you should clean the filter.
• If you notice a decrease in air output or an increase in noise at any time during normal
operation, the filter may be clogged. Clean the filter to return to normal operation.
To clean the filter and reset the Filter Life Counter:
1. First, turn off and unplug the air purifier.
2. Next, remove the front grill. Place your fingers under the handle on the grill
and pull forward, then up. Refer to Figs. 4 and 5 (pg. 6).
