    Why is the change light on my Dri-Eaz DefendAir HEPA 500 Air Cleaner?

      If the 'Change' light is on for your Dri-Eaz Air Cleaner, it could mean that the primary filter is full and needs replacing. Refer to the Maintenance section for instructions on how to replace the filters. Another possible reason is restricted air intake. Check for and eliminate any bends or kinks in the ducting, or try removing the ducting altogether to see if that resolves the issue.
