Product review (3 stars): Humidifier Replacement Water Panel
What can one say about a basic replacement part for a Lennox Humidifier?
It looks like the original. It fit. The price was right.

Regarding the humidifier itself, I noticed that my monthly water consumption increased.
Apparently water enters the top of the water panel, trickles down through it, and the excess water
leaves through drain at the bottom of the unit.

Unlike free standing single room units, there is no reservoir.

Depending upon the mineral content of the water supply, the filter may need to be replaced yearly.
I tried soaking my old one in a dilute vinegar solution to remove the scale. Believe me. It's not worth the
time and mess. The Replacement panel is cheap. Just replace it.
