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. Fig. 9 Filter Reset Button Indicator Light REMOVING / CLEANING THE IFD™ MICRO-FILTER FOR ALL MODELS To remove the ifD™ Micro-filter: • Make certain that the air purifier is OFF and the unit is unplugged. • Push the Filter Release button and then gently lift the filter assembly (Fig. 10a & 10b). The filter assembly will only release if the button is pushed. • Remove the pre-filter (see "Cleaning the Pre-filter"), and set aside. Fig. 10a To clean the ifD™ Micro-filter: • (Optional) After removing the ifD™ Micro-filter from the air purifier, gently run a vacuum cleaner with a nozzle or brush attachment along the filter to pick-up tiny particles (Fig. 11). Repeat on both sides. If your ifD™ Micro-filter appears to have dirt that has not been removed by vacuuming, or if you choose not to vacuum the filter first, please follow the steps below to wash the ifD™ Micro-filter. • Turn the power off and unplug the air purifier. • Remove the ifD™ Micro-filter from the unit. • You can simply rinse the ifD™ Micro-filter under the faucet, or for more thorough cleaning, fill the sink with lukewarm water and add a few drops of mild dish soap (Fig. 12). • Gently swish the filter in the soap solution to clean. • Soak the filter for 2-3 minutes. Do not leave for an extended period of time. • Rinse the filter with clean tap water. • Shake the filter to remove any excess water. • Place the filter with the honeycomb side down on a plush towel (Fig. 13).
