Essick Air FILTERWATCH 127-001 - Manual (Page 8)

3. My red light has not illuminated for quite some time:
Depending upon the condition of the air in the room in which the unit is
operating, the HEPA filter may last anywhere between two and five
years. Make sure you test the unit periodically following the instructions
detailed above.
4. The filter cover does not fit on the unit after I replace the filter:
Make sure the HEPA filter is aligned properly and is not caught on any
internal support piece. Make sure the filters are inserted completely into
the slot. Make sure the filter cover is not reversed and that all tabs are
aligned properly. The HEPA filter is marked "This Side Up."
5. The pre-filter doesn’t look real dirty. Can I continue to use it or try to
clean it:
The pre-filter may be removed and gently vacuumed to remove loose
dust, etc. DO NOT CLEAN THE HEPA FILTER. It will be damaged. To
ensure proper operation of the air purifier, be sure to retest the unit to
see if the HEPA filter needs to be replaced. (Follow instructions in Care
and Maintenance Section). If the FilterWatch light illuminates, change
the filter.
