Cleaning the Filter
The PermaLife™ Filtration System uses a cleanable lter that never has to be changed,
only cleaned. When the lter 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 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 lter to the color coded chart on the inside of the housing. If
the lter color matches the darkest color on the chart, you should clean the lter.
• If you notice a decrease in air output or an increase in noise at any time during normal
operation, the lter may be clogged. Clean the lter to return to normal operation.
To clean the lter and reset the Cleanable Filter Life Counter:
1. First, turn o and unplug the air purier.
2. Next, remove the front grill. Place your ngers under the handle on the grill
and pull forward, then up. Refer to Figs. 4 and 5 (pg. 6).
3. Gently pull on the lter to remove it from the unit. While removing the lter, note
the directional arrows printed on the top of the lter. The lter will be reinstalled
with the same orientation.
4. The label on the top side of the lter points to the side that should be cleaned.
With a vacuum cleaner and upholstery brush attachment, clean the lter until
all particles are removed. Do not use water or liquids to clean.
5. Install the lter with arrows pointing towards the unit. Press the lter rmly into
the air purier. To avoid damaging the lter media, you should press on the
frame of the lter only.
6. Place the front grill back onto the unit. First, line up the tab on the bottom of
the grill with the recess on the purier base and then push the top of the grill
forward until it is closed. NOTE: This unit will not operate unless the grill is in
the correct position.
