What does the CHECK FILTERS light mean and how do I reset it?

The CHECK FILTERS light illuminates after 2,160 hours (approximately 3 months) of operation to remind you to wash the ifD® Particle Filter and replace the Odor & VOC Reducing Pre-filter. To reset it, clean and fully dry the ifD® Particle Filter, then return it to the unit — the CHECK FILTERS light will automatically shut off and the filter timer will reset to zero once the filter is properly seated.
