Cleaning the Cleanable Filter

The PermaLife™ Filtration System uses a cleanable filter that never has to be changed,
only cleaned. When the cleanable filter run time exceeds 2800 hours (approximately 4 to
6 months of use), the Cleanable Filter Life Counter will display 0% life remaining and the
Cleanable 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 cleanable 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 cleanable filter to the color coded chart on the inside of the
housing. If the cleanable filter color matches the darkest color on the chart, you should
clean the cleanable filter.
• If you notice a decrease in air output or an increase in noise at any time during normal
operation, the cleanable filter may be clogged and need cleaning.
To clean the cleanable filter and reset the Cleanable Filter Life Counter:
1. First, turn off and unplug the air purifier.
