FILTER CLEAN INDICATORS HHT-215, HHT-217, HHT-219, HFD-110, HFD-112, HFD-015, HFD-116
This air purifier is equipped with an electronic filter clean monitor to serve as a convenient guideline for
cleaning the ifD™ Micro-filter and pre-filter based on the air purifier's hours of use and operating power
level. This is beneficial because a filter's life depends on the amount of air and contaminants drawn
through it. As you operate your QuietClean® Air Purifier, the filter clean monitor bar
will fill-up from left to right. The bar will continue to fill as you use the unit. Once
the bar is completely full, the Filter Reset button will illuminate — it is time to clean
the filters and reset the filter clean monitor.
Resetting the Filter Clean Monitor (HHT-215, HHT-217, HHT-219 Only)
After cleaning the ifD™ filter, you need to reset the filter clean monitor.
ə Once the ifD™ Micro-filter has been checked and cleaned, the filter clean
monitor will need to be reset.
¢ With the air purifier unit powered on, press and hold the Filter Reset button for
approximately 10 seconds or until the filter bar is clear (Fig. 9a} and LED light goes out.

ə Once you have cleaned the filter, press and hold the Filter Reset button until the LED light goes out.
NOTE: Depending upon your individual usage (environment, hours and power level of operation), you may
need to check and clean the filters more or less frequently.
