Post-filter
The activated carbon filter must be replaced when it is no longer effective in eliminating
odors. The life of the carbon filter will depend on the concentration of odors and
fumes in the air passing through the air cleaner. Under normal operating conditions,
the carbon filter should last from three to six months. The carbon filter must be in
place for the air cleaner to operate.
In the event that you experience problems with the operation of your air cleaner,
please . . .
Make sure electronic cell is clean, dry, and properly installed.
Make sure pre-filter and carbon filter are both properly installed.
Make sure the top cover is properly snapped in place.
