Changing The Carbon Pre-filter
When the Pre-Filter exceeds 4000 hours, the Pre-Filter Life Counters will display
100% life used and you should replace the pre-filter. To maintain proper odor-
removing capability and overall filtration performance, the pre-filter should be
changed every 4000 hours (approximately 6 months of use). If necessary, the
pre-filter can be changed more often. Proper maintenance of the pre-filter will
help extend the life of the HEPA filter. Refer to Replacement Filter Value Pack, for
importance associated with replacing filters regularly.
