Filter Replacement Intervals…
CAUTION: Do not attempt to wash either the activated carbon pre-filter or the HEPA filter. They are not washable and washing will damage the filters.
With proper maintenance, your Honeywell air cleaner is designed to provide years of high efficiency air cleaning. Our recommendations regarding filter replacement intervals are intended as guidelines only, as 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 dust from woodworking or heavy smoking) the useful life of the filter media in your air cleaner may be reduced and require early replacement.
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 activated carbon pre-filter helps protect the HEPA filter by capturing lint and other large particles, and helps reduce normal household odors. It should be checked monthly and replaced at least every 3 months. If there are heavy concentrations of odors, smoke, or large particles in the home, you may need to change the pre-filter more often. We DO NOT recommend operating the air cleaner without the activated carbon pre-filter or without following the filter replacement guidelines.
Whenever the air resistance of the HEPA filter becomes excessive due to the amount of contaminants it has captured, the air volume output will begin to reduce and the sound level of the air cleaner will increase.
If you store your Honeywell HEPA air cleaner for more than 30 days, we recommend:
Removing both the primary HEPA filter and the activated carbon pre-filter from the unit.
Discarding the pre-filter.
Wrapping the HEPA filter in an air-tight plastic bag or plastic wrap. Be sure that the
filter is totally sealed.
To restore the air cleaner to service, unwrap the HEPA filter, install a new activated carbon pre-filter, and reinstall both filters in the air cleaner. See “How to Install and Replace the Filters...” section for proper installation.
