Cleaning the Cleanable Filter
The PermaLife™ Filtration System uses a cleanable lter that never has to be changed,
only cleaned. When the cleanable lter 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 ash (refer to Filter Life Counters for additional information,
pg. 8). This is a reminder that you should check the lter and clean if necessary. The proper
time to clean the cleanable lter depends on usage and the environment. Use the following
list to help determine if the lter should be cleaned:
• Compare the color of the cleanable lter to the color coded chart on the inside of the
housing. If the cleanable lter color matches the darkest color on the chart, you should
clean the cleanable lter.
• If you notice a decrease in air output or an increase in noise at any time during normal
operation, the cleanable lter may be clogged and need cleaning.
To clean the cleanable lter and reset the Cleanable Filter Life Counter:
1. First, turn o and unplug the air purier.
