check/change the HEPA filter and when to r eplace the odor absorbing pre-filter. Depending
upon your individual usage (environment and hours used), you may need to clean/r eplace
the filters more or less frequently.
When the HEPA Filter Indicator Light turns on, it's time to check your HEPA filter. The
Intelli-Check reminder for when to check 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. On average, for best performance your HEP A filter will
need to be replaced every 3 to 5 years. If ther e are sources of large amounts of
contaminant generation (such as dust fr om woodworking or heavy smoking) the HEPA filter
in your air purifier may need to be r eplaced more often. For instructions on how to r eplace
your HEPA filter, refer to section "Replacing the HEPA Filter" in this manual.
When your Pre-filter Indicator Light turns on, it's time to replace your odor absorbing pre-
filter. It should be replaced at least every 3 months. If ther e are heavy concentrations of
odors, smoke, or large particles in the home, you may need to change the odor absorbing
pre-filter more often. For instructions on how to r eplace your pre-filter, refer to section
"Removing/Changing the Filters" in this manual.
Note: We do not recommend operating the air purifier without the odor absorbing pr e-filter.
Your air purifier was shipped with a pr emium carbon zeolite odor reducing pre-filter A Plus.
It can be replaced with either pre-filter A or A Plus. The A Plus pr e-filter features enhanced
odor and household gas absorption performance. Replacement pr e-filters can be
purchased at the Home Depot stor e where you purchased your air purifier, or can be
ordered directly from Home Depot at www.homedepot.com. If you need assistance or have
