|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 pre-filter and one
primary HEPA filter.
|The activated carbon
pre-filter captures large airborne particles, and helps remove odors. The pre-filter should be replaced at
least 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.
|Our recommendations regarding
filter replacement intervals are intended as guidelines only.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 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.
