Filter Clean Indicators HFD-110, HFD-015

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® 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.

Filter Clean Indicator Operation (HFD-015,HFD-110 Only)

•When the filter clean indicator light illuminates, (Fig. 9) it is time to inspect/clean the ifD™ Micro-filter.

•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.
