CLEANING THE IFD ™ FILTERS
To clean the IFD ™ filter:
• After removing the IFD ™ Filter from the air purifier, lay the filter on a flat surface
and run a vacuum cleaner with a nozzle or brush attachment along the filter to
pick-up tiny particles. Repeat on both sides (Fig. 6).
If your IFD ™ filter appears to have dirt that has not been removed by tapping and
vacuuming, please follow the steps below to wash the IFD ™ filter.
• Turn the power off and unplug the air purifier.
• Remove the IFD
™ filter from the unit.
• Fill a sink with lukewarm water and add a few drops of mild dish soap.
• 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 (Fig. 7).
• Shake the filter to remove any excess water.
• Place the filter with the honeycomb side down on a plush towel.
• 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.
• The IFD ™ Filter is NOT dishwasher safe. Do not place the IFD ™ filter in a dishwasher or subject it to
other extreme hot water conditions.
• Do not use any solvents, strong cleaning agents or flammable liquids to clean the IFD ™ filter.
