• LOCATE PRE-FILTER IN THE BOX AND INSTALL BEFORE INITIAL OPERATION.
Refer to “Removing/Changing the Filters” section for proper installation.
• Ensure the air purifier is plugged into a working electrical
outlet and the Power Knob is turned to the OFF position.
• Allow the unit to operate for a few seconds at turbo speed,
then leave the control knob in the turbo position for faster,
more powerful room cleaning, or move the knob to the
sleep setting for quieter operation.
It is recommended you run
your air purifier 24 hours a
day to ensure continuous
cleaning. Portable air
purifiers are more effective
in rooms where all doors
and windows are closed.

The Intelli-Check
™
Filter Indicators serve as a convenient guideline for when to clean the
LifeTime HEPA
™
Permanent Filter and when to replace the carbon pre-filter. Depending
upon your individual usage (environment and hours used), you may need to clean/replace
the filters more or less frequently.
When the
HEPA Filter Indicator Light
turns on, it’s time to clean your HEPA filter. The
Intelli-Check
™
reminder for when to clean the HEPA filter is intended as a guideline only as
the performance of the filter media is dependent on the concentration of the contaminants
to which the system is exposed. If there are sources of large amounts of contaminant
generation (such as dust from woodworking or heavy smoking) the HEPA filter in your air
purifier may need to be cleaned more often. For instructions on how to clean your HEPA
filter, refer to section “Cleaning the LifeTime HEPA
™
Permanent Filter” in this manual.

The air purifier model 50100 series is equipped with a Filter Maintenance Calendar
wheel which serves as a convenient reminder for you to check and replace the pre-filter
and clean the HEPA filter based on the air purifier’s hours of use.
Upon starting your air purifier and upon every pre-filter replacement, roll the pre-filter
change calendar ahead three months to indicate when the next filter replacement is
necessary. Upon starting your air purifier and upon every HEPA filter cleaning, roll the
HEPA filter calendar ahead 6 to 9 months (depending upon use) to indicate when
cleaning the HEPA filter is necessary.
