ELECTRONIC FILTER CHECK REMINDER
This model air purifier has an electronic filter check to
remind you when to check and replace the True HEPA filters
and pre-filter based on the air purifier's hours of use.
A red LED will illuminate when it is time to check/replace
When the True HEPA filters or pre-filter need to be replaced,
the light will remain on until it is RESET. You may unplug the
air purifier without interrupting the filter check.
You should periodically check the filters. Depending on
operating conditions, the True HEPA filters should be replaced
every 12 months and pre-filter every 3 months.
REPLACE WITH TRUE HEPA FILTER
These cleaning intervals are intended as guidelines only.
Performance of any filter media is dependent upon the concentration of contaminants going through
the system. High concentrations of contaminants such as dust, pet dander and smoke will reduce
the useful performance of the filter.
NOTE: None of the filters are washable. DO NOT immerse them in water.
To RESET the Electronic Filter Check:
When the Check Filter LED remains on and solid, it is time to replace the Odor Reducing Pre-filter and
reset the filter monitor. With the unit powered ON, press the FILTER RESET button below the Check Filter
LED and hold for approximately 2 seconds until the light turns off (Fig. 4).
When the LED illuminates and is flashing, it is time to replace the True HEPA filters and reset the filter
monitor. With the unit powered ON, press FILTER RESET button and hold for approximately 2 seconds
until the light turns OFF (Fig. 4).
Manual (or Early) Reset of Electronic Filter Check
Depending on your individual usage (environment and hours used), you may need to replace the filters
more or less frequently. Each time you replace your filters, you should reset the filter monitor. You may
manually reset the filter monitor for the pre-filter or the HEPA filter, or both. If you change the pre-filter
or True HEPA filter before the Check Filter LED is illuminated, it is possible to reset the filter monitor.
