Filter Replacement...
Important...
With proper maintenance, your Honeywell air cleaner is designed to provide years of
high efficiency air cleaning.Your Honeywell air cleaner contains two filters: one activated
carbon prefilter and one primary HEPA filter.
The activated carbon prefilter helps capture large airborne particles, and helps remove
odors.The prefilter should be replaced every 3 months.You may need to replace the
prefilter 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.
Our recommendations regarding filter replacement intervals are intended as guidelines
only and are based upon reasonable filter life expectancy in homes with normal levels of
particle generation. If there are sources of large amounts of particle generation (such as
woodworking or heavy smoking) the useful life of the activated carbon prefilter and HEPA
filter in your air cleaner may be reduced .
Whenever the combined air resistance of the activated carbon 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 prefilter is clogged and must be replaced.
2. If the unit continues to pulsate after a new prefilter is installed,
the useful life of the HEPA filter has been reached and it must be replaced.
Replace the activated carbon prefilter at least every 3 months. The activated
carbon prefilter is the element of your air cleaner that helps remove odors and
gaseous compounds. 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 prefilter more often.
We
DO NOT recommend operating the air cleaner without the activated carbon prefilter
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 omit the odor
captured.
CAUTION: Do not attempt to wash either the activated carbon prefilter or the HEPA filter.
They are not washable and washing will damage the filters.
