Lennox Humidifier Filter Holder 21N39

About the Filter Holder

On some flow-through style humidifiers, a filter holder secures the top of the wick filter or water evaporator pad and channels the incoming water through the filter or pad. If the filter holder is clogged with mineral deposits or damaged, the incoming water can easily overflow. Inspect the filter holder for obstructions or damage and replace with a new one if necessary.
