This model air purifier has an electronic filter check to
remind you when to replace the Dual Action HEPA-Type
Filter based on the air purifier’s hours of use.
An LED light will illuminate when it is time to change
the filter.
You should periodically check the filter. Depending on
operating conditions, the filter should be replaced every 4
months for best performance.
REPLACE WITH HEPA-TYPE FILTER
TO RESET THE ELECTRONIC FILTER CHECK:
When the filter indicator light remains on, it is time to change the Dual Action HEPA-Type Filter and reset the
filter monitor. With the unit powered on, press the filter reset button next to the LED Filter Indicator Light and
hold for approximately 5 seconds until the light turns off (see Fig. 3). Depending upon your individual usage
(environment and hours used), you may need to replace the filter more or less frequently. Each time you
replace your filter, you should reset the filter monitor reset button.

ACCESSORIES AND REPLACEMENT FILTER
WARNING: Filters may be harmful if ingested. Avoid breathing dust when changing filters.
The Dual Action HEPA-Type Filter has a built-in odor adsorbing pre-filter. This Dual Action Replacement
Filter is not cleanable , and should be replaced every 4 months to help ensure optimal performance.
The replacement interval is intended as a guideline only. Useful life expectancy of any filter media is dependent
upon the concentration of particles going through the system. High concentrations of particles such as dust, pet
dander and smoke will reduce the useful life of the filter.
