4.2. Check Filter Indicator
After a total of 3,000 cumulative hours (125 days) of operation since the last reset, the
Check Filter
indicator on the LED Display will illuminate as a reminder that you should check the filters and clean or
replace as necessary. If the prefilter is dirty hand wash, rinse and hang to dry, DO NOT MACHINE WASH.
Check the HEPA filter against the color shade guide on the filter frame
to see if replacement is necessary.
Filters and ultraviolet germicidal lamps should be replaced at least once every 12 months to provide
optimal efficiency and performance. If your air quality is particularly poor, you may need to replace more
often.
