FREQUENTLY ASKED QUESTIONS

How often is cleaning required?
The IFD ™ filter reset light will illuminate to indicate that the IFD
recommend cleaning the filter about once a month depending on the air quality of the room.
I just cleaned my filter but the filter indicator bar is still showing it is dirty, what's wrong?
Each time you clean your filter you must reset the filter life indicator. It is a timer driven indicator to be
used as a guideline, but does not represent the actual amount of dirt in the IFD
the appropriate button for up to 10 seconds and when you let go, the filter indicator bar should be
reset.
The filter indicator bar on my unit is completely full but my filter doesn't really look dirty.
The filter indicator on your unit is timer-based and does not measure the amount of particles in the
IFD ™ filter. It is possible that your filter indicator could indicate that the filter is dirty but some particles
are so small that they cannot be seen but are present in the filter. We recommend cleaning the IFD
filter (see Removing/Cleaning the IFD
My filter bar says my filter is still relatively clean but when I checked my filter it was really dirty.
In conditions where smoke, pets or air with a lot of contaminants are present it is possible that the filter
could be dirty sooner than indicated on the indicator. The filter life indicator on your unit runs on a
timer and if there are more particles in your air than in an average home, your filter could capture
airborne particles sooner than indicated on the display. The indicator is intended to be used as a
guideline and individual environmental conditions will vary.
Is the IFD ™ Air Purifier considered an ozone generator?
No. Ozone generators produce large amounts of ozone and the EPA considers these unsafe for
household use.
