Changing the Pre-Filter
When the Pre-Filter exceeds 1400 hours (refer to Filter Life Counters for additional informa-
tion, pg. 8), the Pre-Filter indicator will turn on as a reminder that you should replace the
pre-lter. To maintain proper odor-removing capability and overall ltration performance,
the pre-lter should be changed every 1400 hours (approximately 3 months of use). If
necessary, the pre-lter can be changed more often. Proper maintenance of the pre-lter
will help extend the life of the HEPAtech

lter. Refer to Obtaining Replacement Filters (pg.
13) if you need help nding replacement lters.
To change the pre-lter and reset the Pre-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. The pre-lter is attached to the inside of the grill with hook tape. Pull gently
on the pre-lter to remove it. Refer to Fig. 9.
4. If needed, use a soft damp cloth to wipe o the grill.
5. Install the new pre-lter by placing it in the grill and pressing gently on the
pre-lter so that it adheres to the hook tape. You may notice a few black par-
ticles coming o the pre-lter. Those particles are part of the odor-removing
activated carbon and will be collected on the lter during regular use.
