This air cleaner is equipped with Intelli-Check Filter
TM
Monitors to serve as a convenient
guideline for replacement of the pre-filter and HEPA filter based on the air cleaner’s
hours of use and operating speed. This is beneficial because a filter’s life depends on
the amount of air and contaminants drawn through it. Each filter bar will fill up from clean
to dirty as its expected filter life is used up. Once the bar is completely full, it is time to
check / replace the filter.
• To move between the PRE-FILTER bar and the
HEPA FILTER bar, quickly press the FILTER button
(Fig. 6a).
• To RESET a filter bar that appears on the display,
press and hold the FILTER button for 5 seconds, or
until the filter bar clears to CLEAN status (Fig. 6b).
The Intelli-Check
™
Filter Monitors calculate the
expected filter life based on an assumed average
operating time of 12 hours a day on medium speed.
Therefore, it will indicate replacement of the Pre-filter
in about 3 months, and the HEPA filter in about 1
year and 9 months. Depending upon your individual
usage (environment, hours and speed of operation),
you may need to check and replace the filters more
or less frequently.
