FILTER CLEAN INDICATORS HFD-110, HFD-015
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
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.

NOTE: Depending upon your individual usage (environment, hours and power level of
