REMOVING / CLEANING THE IFD
This IFD ™ air purifier is equipped with an electronic filter indicator to serve as a
convenient guideline for cleaning the IFD
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 IFD ™ 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.
To reset the filter clean indicator:
• With the power on, press and hold the Filter Reset button
for 10 seconds, or until the filter bar clears itself (Fig. 5).
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 ™
• 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.
To clean the IFD ™ filter:
• After removing the IFD
with a nozzle or brush attachment along the filter to pick-up tiny particles (Fig. 7).
