Changing the Filter
When the filter exceeds 2800 hours (approximately 4 to 6 months of use), the Filter indicator
will turn on as a reminder that you should replace the filter. (Refer to Filter Life Counters for
additional information, pg. 8.) This is a reminder that you should check the Filter and replace if
necessary. The proper time to change the Filter depends on usage and the environment. Use
the following list to help determine if the filter should be changed:
• 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 replace 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. Replace the Filter to return to normal operation.
To change 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 new Filter will be installed with the
same orientation. Refer to Fig. 10. Once removed, the used Filter can be discarded.
4. Look at the directional arrows printed on the side of the Filter. Install the Filter with arrows
pointing towards the unit. Refer to Fig. 10. Press the Filter firmly into the Air Purifier. To avoid
damaging the Filter media, you should press on the frame of the Filter only. NOTE: THIS
UNIT WILL NOT OPERATE UNLESS FILTER IS INSTALLED CORRECTLY AND SEATED
PROPERLY.
5. 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.
6. Plug in the unit.
7. To reset the counter to zero hours and turn off the indicator, simply press and
hold the Filter Reset key for three seconds. Then, you must release the Filter
Reset key and then press and hold the Filter Reset key again for three seconds
to turn off the Filter Indicator.
