exceeds 1400 hours, the
Pre-Filter indicator will
flash “00%” as a
reminder that you should
clean the Pre-Filter and
change the Carbon Odor Filter. To maintain
proper odor-removing capability and overall
filtration performance, the Pre-filters should be
cleaned and the Carbon Odor filters replaced
every 1400 hours (approximately 3 months of
use). If necessary, clean the pre-filter and
change the odor filter more often.
