Cleaning the Filter
The 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. 9). 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 hous
-
ing. 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).
3. Gently pull on the filter to remove it from the unit. While removing the filter,
note the directional arrows printed on the top of the filter. The filter will be
reinstalled with the same orientation. Refer to Fig. 12.
4. The label on the top side of the filter points to the side that should be cleaned.
Refer to Fig. 12. With a vacuum cleaner and upholstery brush attachment,
clean the filter until all particles are removed. Do not use water or liquids
to clean.
5. Install the filter with arrows pointing towards the unit. Refer to Fig. 12. Press
the filter firmly into the air purifier. To avoid damaging the filter media, you
should press on the frame of the filter 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 purifier base and then push the top of the
grill forward until it is closed. Refer to Figs. 6 and 7 (pg. 7). NOTE: This
unit will not operate unless the grill is in the correct position.
