How To Clean Pre Filter Honeywell Air Cleaners
Tip
Reset the filter monitor which activates the red light. There will be a reset button adjacent to the red light.
Warning
The main filter—Stages 2 and 3, can't be washed like the Stage 1 pre-filter. Washing it will destroy it. Replace the main filter.
Some Honeywell air cleaners have four filters. They can include a Stage 1, washable pre-filter; a Stage 2, odor lock carbon filter; a Stage 3 99 percent HEPA filter with antimicrobial treatment; and a Stage 4 electronic ionizer. The Stage 1 Honeywell air filter pre-filter helps pick up large airborne particles that come in through the front grille. A red LED light will come on when it's time to change or wash the filters.
Step 1
Turn the air cleaner off, and remove the Stage 1 washable particle pre-filter. The filters are behind the front grille of the Honeywell air cleaner.
Step 2
Take the pre-filter outside and shake it. Examine the pre-filter to determine if by shaking it you have cleaned it. If there is still dirt and dust on it, proceed to the next step.
Step 3
Wash the pre-filter by hand under warm water.
Step 4
Allow the pre-filter to dry and re-insert it.
