Product review (5 stars): Aprilaire 35 Water Panel - Great
This 2-pack is fantastic.  The furnace guy came to do his annual cleaning and replaced our Aprilaire water panel before I purchased these.  He told us we could find them cheaper elsewhere, but we wanted it changed while he was here.  He charged $45 for one of these.  Amazon was a terrific buy and they came in the same, identical OEM box as the one the furnace guy installed.  Will definitely be buying these again and again.
