HHT-215_HHT-217_OM.qxd 10/20/06 5:02 PM Page 4 REMOVING / CLEANING THE IFD™ FILTER This air purifier is equipped with an electronic filter indicator to serve as a convenient guideline for cleaning the IFD™ 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 bar indicator 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 indicator. 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. To remove the IFD™ filter: Fig. 6a Fig. 6b • 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. 6a & 6b). The filter assembly will only release if the button is pushed. • Remove the pre-filter (see "Cleaning the Pre-filter"), and set aside. Fig. 7 Fig. 8 To clean the IFD™ filter: • After removing the IFD™ 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. 7). Repeat on both sides. If your IFD™ filter appears to have dirt that has not been removed by vacuuming, please follow the steps below to wash the IFD™ filter. Fig. 9 • Turn the power off and unplug the air purifier. • Remove the IFD™ filter from the unit. • Fill the sink with lukewarm water and add a few drops of mild dish soap (Fig. 8). • 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. 9). • Note that the filter may still be discolored even after washing. This is acceptable and will not affect performance. • Allow the IFD™ filter to dry for a few hours or overnight. • When the IFD™ filter is completely dry, place back into the air purifier. CAUTION: • Never place a wet IFD™ filter in your air purifier. • Do not use any solvents, strong cleaning agents or flammable liquids to clean the IFD™ filter. 4
