FILTER CLEAN INDICATORS HFD-110, HFD-015, HD110
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. When the Filter Reset button illuminates, it is time to clean the filters and reset the filter clean
monitor.
