Filter Replacement...
With proper maintenance, your Honeywell air cleaner is designed to provide years
of high efficiency air cleaning. Your Honeywell air cleaner contains three filters: one
activated carbon pre-filter, one primary HEPA filter, and one CPZ
media cartridge.
The activated carbon pre-filter helps capture large airborne particles, and helps remove
odors. The pre-filter should be replaced every 3 months. You may need to replace
the pre-filter more often if the unit is used in a smoking environment or if unpleasant
odors persist.
The primary HEPA filter should remain effective for 1 to 3 years, depending upon the
environment in which the air cleaner is operating. Honeywell recommends changing the
HEPA filter based upon operation conditions–every 3 years for light usage, 2 years for
normal usage and 1 year for heavy usage.
The CPZ
TM
sorbent media cartridge should be replaced every 12 to 18 months, or more
frequently if its odor adsorption capacity has been consumed. When its adsorbing
capacity has been reached, it will emit a persistent foul odor indicating that it should
be replaced.
Our recommendations regarding filter replacement intervals are intended as guidelines
only. The life expectancy of any 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 woodworking, painting or heavy smoking) the useful life
of the filter media in your air cleaner may be reduced.
Whenever the combined air resistance of the activated carbon pre-filter and primary
HEPA filter becomes excessive due to the amount of contaminants they have captured,
the air cleaner will begin to audibly pulsate. Instead of a steady stream of air, rapid
"puffs" of air may be felt at the outlet slot. When this occurs, one of two conditions exists:
1. The activated carbon pre-filter is clogged and must be replaced.
2. If the unit continues to pulsate after a new pre-filter is installed, the useful life of the
HEPA filter has been reached and it must be replaced.
Important...
Replace the activated carbon pre-filter at least every 3 months. The activated
carbon pre-filter is the element of your air cleaner that helps remove odors and
gaseous compounds and helps protect the life of the HEPA filter. Under normal
household conditions the odor adsorption capability will be used up in about 3
months. If there are heavy concentrations of odors, smoke, or gases (such as tobacco
smoke) in the home, you may need to change the activated carbon pre-filter more often.
We DO NOT recommend operating the air cleaner without the activated carbon pre-filter
or CPZ
TM
sorbent media cartridge because the primary HEPA filter does NOT absorb
odors or gaseous compounds. In fact, the HEPA filter may become contaminated by
these odors and begin to emit the odor captured.
CAUTION: Do not attempt to wash the activated carbon pre-filter, HEPA filter or the
CPZ
TM
sorbent media cartridge. They are not washable and will be damaged if cleaned.
