Question about Emerson HDC12 Humidifier
The CF comes on after 720 hours of operation (while continuously plugged in). Really stands for Check FIlter, not Change FIlter.
Just pull the plug and let is stay unplugged for 30 seconds or so. When you plug it back in, it will be reset for another 720 hours.
