Reduced Air Flow or Poor Filtering
• The intake or outlet grille
may be blocked. Make
sure nothing is in front of
or on top of the air purifier.
• The carbon pre-filter or
the HEPA filter may be
clogged. Check the filters
with the filter gauge and
replace them, if necessary.
Troubleshooting Guide
The following section provides the solutions to many
common problems and questions. If your air purifier is
not working correctly, review these solutions first. If your
problem is still not solved after reviewing this guide, call
our toll-free customer service number, listed on the front
cover of this manual, for assistance.
The Air Purifier Will Not Turn On
• Are the intake grille and
the outlet grille installed
and locked into place?
• Is the air purifier plugged
into a powered outlet?
• Is the fan speed knob
turned on?
Replacing the HEPA Filter
The HEPA filter will normally last about 12 months before it
must be replaced, or approximately every fourth time the
carbon pre-filter is replaced.
If the filter check gauge indicates that the filter requires
replacement, it is recommended that you first replace the
carbon pre-filter and then use the filter check gauge to check
the filter again. If the colored cylinder still does not float up
the gauge, the HEPA filter must also be replaced.
Turn off and unplug air purifier.
Remove the used HEPA filter by
gripping the sides and pulling
outward, as shown. Discard the
used filter. It cannot be cleaned.
Obtain a replacement HEPA
filter. Insert the unwrapped
HEPA filter, hook fastener
side out, into the air purifier.
NOTE: Improper filter installation
will result in poor air filtration.
